Like a few others, I'm surprised by the negative comments on the thread here. 

I've not been to the restaurant before (or any in the chain) but I came with a Hen Do on a Friday night (so a large group of drunk and possibly annoying women). We didn't experience any negativity! We all bought some bottles of bubbly and because we were a large group we prebooked - and rather than order individual dishes we prepaid a set amount and were bought out lots of different dishes. For starter, we had a mountain of satay chicken, spring rolls (and some other bits that I was too intoxicated to actually remember) and for main Massaman Curry, Green Thai curry, Pad Thai and sticky rice. 

I actually really liked the atmosphere. It was super snowy so it was really warm, cosy and welcoming inside. 

Don't be put off by the negative comments - go find out for yourself!


Who doesn't love a BYOB night?! We had a table for 16 book for a friends birthday and the food was so tastey! If you are looking for a relaxed dining environment I wouldn't say this is it, the place its self does feel quite hectic, and we did have to wait for our table a while (which was pre booked). The style of dining for a large group was great starting with satay chicken skewers, spring rolls and chicken wings all to share, followed by two curries and a pad thai. There was definitely plenty of food to go around, and once we were seated there was no rush to leave.

Food is not fresh, a very bad example of a Thai restaurant. Probably the worse I have been too. Staff are rude, arrogant and dismissive. 


I went to this restaurant last night and now that I came here to write a review, I'm surprised by the negative comments! I didn't know they have a restaurant in Brixton, so I can't compare the two. In fact, I didn't know about this place overall, because I rarely go south of the river. It was my friend's suggestion and we were both happy with our choice when we left.

It's apparently always busy, hard to get a table. That's why the service is super fast. Putting the bill on our table without us asking was just a polite way to say your time is over and we have more customers waiting to be seated. But I don't consider this as a rude behaviour at all.

The food was authentic, good quality and delicious. Make sure to get the dessert that is banana fritters, can't remember its original name. Even though I have never been to Thailand, it was as if I was eating it there. Basically it was a banana cut in half, dipped in a batter and fried, served with vanilla ice cream and honey, it was quite an experience! Don't miss it!

I saw all the reviews about rude staff and being kicked out quickly, but had the opposite experience. Staff were extremely friendly, helpful and did not rush us. It's a great BYOB joint, and the thai food is very authentic, cheap and delicious. A local favourite!

"Things don't come for free" quoted by the owner of the restaurant when asked what the erroneous £7 added to the menu consituted. Don't frequent if you expect service or quality. It's popularity rides on free booze far above food.

Food is fab but booking system is painful and they literally kick you out of your seat at the 1.5hour mark. Great for a cheap eat as you can BYOB but be prepared to be in and out quickly...


Authentic and memorable Thai food at cheap and cheery prices, popping into Kaosarn is always a pleasure. Remember to BYOB and you can launch straight into the spring roll starters followed by the Pad Thai main (try mix and matching prawns and chicken).

I never really stray from this tried and tested routine as it's always delicious. Not sure about the desserts? Definitely order the fried bananas and ice won't regret it, especially not after your fourth glass of Lidle rosé!

It makes me want to visit Thailand every time.


KaoSarn is a great place if you are looking for delicious, quick and cheap food.

I've been a few times and it has never failed to disappoint. Most recently, I chose KaoSarn as the destination for my birthday meal as I've only ever had good experiences there. Once again, I was more than happy. I can't speak personally for everyone else's dishes but, the Moo Ping (Bangkok grilled pork skewers marinated with palm sugar and spice) I tried were tender and packed full of flavour

This was followed by the Pla Chu Chi (salmon steak topped with red curry sauce and fresh chilli) which packed a spicy punch.

What's even better is KaoSarn is BYOB - meaning you can pop to the Sainsbury's a few shops away and pick up a bargain to accompany you dinner.

The only downside to KaoSarn is they do like to turn the tables over pretty quickly. For nine people we were allocated an hour and a half for dinner and, as soon as that time was up they were giving us the bill and seeing the next group in.

The rudest service I've had in London. Food was average tasteless curry and greasy starters. Avoid

I have been to Kao Sarn many many times since they first opened in Brixton. It used to be good value, tasty food and a nice buzzy atmosphere if at times a bit hectic. However I went back to this branch in CJ this week and it has seriously deteriorated. The quality of the food has changed (green curry now has practically no kick at all)  and some of the portion sizes have literally halved! The tiniest pad thai I have ever seen!!! More disappointing however was the appalling service - I am used to this place having a fairly quick turnover but to have your food whisked away while you are still eating and the bill thrust in front of you when you have been there less than an hour despite having ordered staters and mains was outrageous. When I pointed this out to the waitress and explained that I had seen recent poor reviews re the service I was simply told, 'yeah, we don't really care'. Sums it up perfectly. Shame. 


I love this place - cheap, BYO and the food is great. It's busy, especially at the weekend, so get there early or book ahead. It's good for vegetarians with 4-5 dishes that you can have with tofu, although be sure to tell them 'no fish sauce' if you're not a fish eater. I was a little bit disappointed with by beef massaman most recently - just lots of beef and a couple of potatoes, no other vegetables really - but I've had other dishes there including the green curry and pad thai, which have been excellent. Be warned, they only take cash!


I visited this CJ Kaosarn for the first time on Saturday for a birthday party. It is a great venue for a table of c.20 or so and BYOB makes the night very easy in terms of dividing up the bill at the end of the night - no awkward conversations to be had. The menu is £25 for the set menu - starter platters (spring rolls, ribs, chicken satay) and a selection of main courses (pad thai, green chicken curry, beef massaman and chilli chicken, and steamed rice). There was an abundance of food although perhaps for the variety and for thai food, £25 is still a little steep. Of the starters, nothing overly stood out... the chicken satay was nice. The pad thai was the hero of the night, although both chicken dishes were tasty. We had a great night, with great company and free champagne provided by a friend who has a very handy job in the wine industry so we had a great time and enjoyed the food a lot. I can see why perhaps it would be somewhat underwhelming if you were in a less festive mood though.

The worst restaurant experience of my life. Service was truly awful. The manager is the rudest, most obnoxious person to ever have the displeasure of serving anyone. Repeatedly told us to "move" and "make room" for people who never preceded to show up. There are literally thousands of better places to spend £30 for a meal. AVOID!!!

Food was lovely, but the service was appalling. I have never been spoken to so rudely and being shouted at in the middle of the restaurant is not acceptable.  I would not recommend this restaurant to anyone until the owners sort out their attitude and service.

Yeah, just call to book a table, but it was already full for tonight (Friday). Apparently you have to book table a week in advance. And well, the woman at the telephone was really quite rude. Hope at least the food can impress me.

A great local, the food is always delicious and the need to book is testament to its popularity. An affordable addition to St John's Hill.

Awful place. Our starters were greasy and tasteless, but the real problem was the main. My main was listed as a pepper chicken dish with rice and spicy sauce - the rice was served in the plastic bag it was microwaved in and the spicy sauce was bog-standard sweet chilli dipping sauce. My chicken, though, was KFC type deep fried chicken which was actually raw inside. The waitress took the chicken away with no apology and without telling us whether she was going to replace the dish. By the time we'd finished my companion's (mediocre and over salty) pad thai, we asked her what was happening with my main to be told that they were not sure whether to prepare a new version. At this point we got the bill. I don't expect to be served raw chicken in a restaurant, but what was particularly disapointing was that the staff made no attempt to explain, apologies, or attempt to rectify the situation. Don't go

This is the best Thai food outside of Thailand - a taste sensation. Love this place and I think it is better than the Brixton restaurant but love both! Can't recommend more highly. Great to sit outside on a summers evening, inside upstairs also fab, down the back is fine but prefer the former. BYO is great, prices very affordable. I have been with my work friends a few times and we are all looking forward to returning. Staff have always been pleasant to us and the manager Gisele always polite to us and recommends great dishes- she is quite a character.

Enjoyed the food but the experience was completely tainted by the attitude of the staff, who were very disinterested and rude. Staff, in my opinion, make a restaurant. For that reason, I will not be returning to this place nor would I recommend it to others.

Such good value for money! Amazing food & service, affordable, perfect for a group BYO. Would highly recommend.

I have lived in Thailand for several years, I'm married to a Thai and have eaten Thai food all over the world so when I say this I think I know what I'm talking about. We visited yesterday afternoon - it was not busy with maybe 5 or 6 other people in the restaurant. The service was pleasant enough - we ordered a pad thai, two starters, a main course and a side of sticky rice - with three soft drinks that came to over £35. Thai food is seldom that good outside of Thailand so I was not expecting anything special, but the food here was ABSOLUTELY the WORST Thai food I have ever had ANYWHERE and a total rip-off in terms of value. We left having eaten less than a third of what we had ordered and will NEVER be going back ! Verdict - Shite!

I visited this restaurant for the first time this week. We were rushed to place our order, we were spoken very rudely by a very masculin looking female member of staff. The service was very average and the food was nothing to were home about. Your best off trying Tamnag Thai in Crystal Palace. Needless to say I will not be visiting this restaurant again.

Good food but TERRIBLE service - disgusting the way that the lady manager speaks to customers, I do not recommend this restaurant at all.

A large group of us went to Kaosarn on Saturday night and had a fantastic time. The food was absolutely delicious, the staff super friendly and extremely helpful with different dietary requirements. It is such great value for money and being BYO keeps the cost down as well. I will be recommending it to everyone I know and going back myself.

Food was great but this was overshadowed by the fact that as we left, we were told to never come back as our 10 pound tip wasn't enough and was "cheap," according to the old woman that runs it. We are never going back to this appalling service and treatment and in future will tell our local friends to stay away!

Incredibly rude staff - they called me and me abuse down the phone, saying I was rude and that my father should be ashamed simply because I failed to cancel my booking. Based on the below average reviews they have been geting, customer service should be high on their agenda. That is not a way to treat a customer. Wouldnt recommend.

Can't fault the food, but the service was appalling. Our quiet Wednesday night birthday celebration for three was rushed from the start and then we were made to feel like criminals for wanting to finish our drinks. Turfed out by a woman with a sadistic smile and told if we were going to be so cheeky "then don't bother coming back". We wont be.

I went with three Frenids the food was the best I have hot and well presented and the service was really good. We never book and was told they were fully booked and said we had a hour to eat we finnish Just after the hour we was not rush and made very welcome,

I'm a huge fan of Kao Sarn in Brixton Market, but the menu is more extensive here, and it's much calmer and relaxed. It's the best food I've eaten outside of Thailand, the real deal with incredible, subtle flavours. Being BYO makes it a huge bargain too. I particularly recommend the seabass, and the fried shrimp starter. Both are oustanding. Personally I absolutely love the no-nonsense service - can't stand it when service is cloying or smarmy. Would highly recommend.

Food is nice but not spectacular. Service is appalling. The rudeness of the woman who seemed to be in charge was beyond belief. With a lot of other good value Thais around there is no point in going here. From looking at the reviews below this seems to be a bit of a theme with this place.

Love it! Delicious, fresh food, and really friendly staff! Also, it would be cheap even without the BYOB! Hugely recommended.

Been to the Brixton one loads - this one is definitely less 'scene' than there but still excellent and offers a calmer dining experience. Food is difficult to fault and BYOB is just always a winner recession or otherwise! Go and eat here.

Food is ok ...... I suspect that this place is popular becauise of the BYOB rather than the food quality. The service, however, is TERRIBLE, I have never known such rude waiting staff or actually ever been spoken to in such a rude manner. We will not be returning here again.

Amazing Yhai food and very friendly staff. A great addition to St John's Hill!
