Rhubarb Bastard at Peckham Springs Bar



If you love negronis, you’re in luck: this trendy spot in Peckham has come up with a lighter, summery version of the popular Italian aperitif, with a nominal amount of calories. Aperol, lillet wine, Beefeater gin, fresh grapefruit and rhubarb bitters is all you get in a Rhubarb Bastard – so at just £6 a pop, the only thing you’ll need to worry about is pacing yourself.

Venue says Nestled under railway arches, Peckham Springs boasts a winter garden, a buzzing cocktail bar, a performance space and an art gallery.

The Ricemobile at High Water



The pleasure-seekers that frequent this popular Stokey haunt know that High Water never fails to deliver, which is why it’s probably the only place that could get away with a drink called the Ricemobile. But once you get the lols out of your system, you'll realise this is actually one serious drink. This yummy low-calorie combo is made up of honey dew melon, bourbon, lemon and genmaicha tea roasted with brown rice, which is rich in fibre, iron, natural sugars and vitamin D.

Carrier Pigeon at Discount Suit Company



East London's Discount Suit Company refreshes its cocktail list quite frequently, but if you speak to the right guy, you might be able to wrap your tastebuds around its infamous Carrier Pigeon – a vegan-friendly, low-calorie potion of white rum, lavender, lemon and prosecco. It’s a wonderful drink that lives up to DSC’s rep for excellent and creative booze.

Chevril Root Bellini at Grain Store

King’s Cross


Grain Store in King’s Cross is big on the veg, so offers all sorts of clever drink infusions that will also help you cram in your five-a-day. For a classy little number, go for the chervil root bellini. Prosecco is known for its low calorie count and chervil is naturally sweet, so you can knock back a couple in the knowledge that this delicious moment on the lips won’t mean a lifetime on the hips.

Green Grocer at Barrio Brixton



Designed by those Latin lovers at Barrio Brixton, the refreshing Green Grocer is one of the closest things you’ll find to a healthy mojito. This thirst-quencher is jam-packed with kiwi, coriander, cucumber, lime and sesame seeds, delivering all sorts of vitamin-y goodness – but the real clincher is that for those who don’t do refined sugar, you won’t get a drop of it in this low-calorie cocktail, as Beefeater gin substitutes the sugar-based white rum.

Bee's Knees at Cocktail Trading Company

Farringdon and Smithfield


The wacky Cocktail Trading Company is brilliant at whipping up experimental concoctions, but surprisingly, their healthiest cocktail is a simple one. The Bee’s Knees is a flavour-rich gin, honey and lemon juice concoction that’s a throwback to the Roaring Twenties, but it's the perfect brew for health-conscious millennials who still want to get their buzz on. It’s less than 200 calories – and fyi, gin is one of the better boozes if you’re sticking to a diet.

Haiboro Loco at Worship Street Whistling Shop



Trust this slummy, Victorian-style speakeasy to craft a flavourful, low-calorie drink like the Haiboro Loco. Japanese Nikka Blended whisky provides the fruitiness, but throw in the herby triple root tincture, mint, dill and a saline solution (with the tiniest bit of sugar) and you have one potent glass of liquour that might be better than your average cocktail. That said, you will feel this one in the morning…

Skinny Watermelon Martini at Christopher's

Covent Garden


When it comes to martinis, this upmarket American restaurant in Covent Garden has got the right idea – offer something for everyone. Of the 24 versions to choose from, calorie-counters can have the watermelon martini – a lovely bevvy that’s only 130 calories. It’s made from vanilla-infused fair quinoa vodka and fresh watermelon and tastes as incredible as it sounds.

Clarified Bloody Mary at Duck & Waffle

Liverpool Street


The bloody mary is a weight-watcher’s dream: it’s nutritious, delicious and won’t pile on the pounds as the only thing sweet about it is that it’ll sort out your hangover. The one at Duck & Waffle is a remarkably lighter version of the classic, but that’s down to the brilliant handiwork of the venue’s award-winning mixmaster Richard Woods. It’s made with gin, spices and a bloody mary consommé – oo-er! – which gets you a classy, low-calorie drink that still packs a glorious punch.

The Connaught Martini at The Connaught Bar



Whether you like it straight, shaken or served on the rocks, the martini in its simplest form is the one alcoholic low-calorie drink you can raise a glass to. The best in town comes courtesy of the super-swanky Connaught Bar, where a martini is rolled out on a trolley and made right beside you. It's an experience that'll cost you nearly £20, mind you, but even calorie-counters deserve a treat day.

The best martinis in London

It’s the greatest cocktail. For some people, it’s the only cocktail. So perfect in its simplicity – gin or vodka, vermouth, garnish – that it should be easy to make. But bars that achieve perfection still aren’t as easy to find in London as they are in New York City, Chicago or San Francisco. So here are our top ‘tini hotspots, with a bias towards those that do martinis with little variation from classic principles. But don’t worry, you’ll still find a few audacious innovations in our list as well.
