Itsu is a pan asian / Japanese inspired chain restaurant all over London and some other big cities in the UK. It's great, varied and cheap, and when you need to find some easy gluten free alternatives then Itsu can be a good place to turn to as chances are you'll find one on most of the big high streets. The chain was set up by the people who first set up Pret a Manger and there motto is "eat beautiful". They try and make food to keep you skinny, "less fat and more bounce". There are also two actual restaurants in Notting Hill and Chelsea where chefs are employed to keep up this ethos and supply you with a proper meal too. As well as gluten free you can find low carb, mayonaise free and lots of other options. Enjoy and be beautiful.
