The waiters were lovely to me, but their recommendation of how much food to order doesn't actually come to that much, the portions are either quite small or more like snack foods than something you'd expect in a restaurant.
More than being pure anything, there seems to be a bit of a mix of Asian flavours rather than pure Japanese; some of which were great but for people who eat fish and not meat like myself it can be a bit off putting if all that's on offer as 'flesh' is pork and steak when I went there - although this has since been updated to include a few more options, including salmon. I subsided on appetisers. The dishes are also expensive for what you get, extremely overpriced for what you're getting, which makes me slightly wary although the food wasn't too bad in itself. The sushi however was quite good, with well mixed sauces. The jalapeño crab rolls in particular were nice, as were the prawn tempura rolls.
There's also a nice atmosphere, the music is quite fitting for the style of the restaurant and it's quite nice to go somewhere that isn't constantly playing the chart top 10. It's much more fun eating to this than it is to ill advised tween bopping music, and you can actually have a conversation and enjoy the experience.
However, like many people here I was also disappointed by the bathrooms. I think there's a time and a place for that sort of decoration, and this restaurant isn't it. Whilst I wouldn't call it 'pedophile porn' as I know where the art originates and the illustrative style of some manga and anime and this seems more than a bit harsh, I don't find it very tasteful in a restaurant when I'm using the bathroom to have to look at this. It's more than a little disappointing.
Overall, I might go here again; but only if the bathrooms are altered and some more meat free options are available. It's very uncomfortable to have to see that style of art in a restaurant, and while I appreciate I now have the choice of salmon or aubergine, it's more than a little expensive for what it is. I'd much prefer to spend my money elsewhere, where it's more for less and I don't have to see that kind of display.
