Bento boxes are great and they do lunch time meals. The fried noodles I was not so fond of but I highly recommend the bento boxes. The food is fresh and service is good. They offer a choice of authentic japanese drinks and the price overall is not too expensive.
Seating may not be to everyone's taste but is the style of japan. It can get abit cosy but I did not go at peak times.

Was delighted at the quality of the service - but there was one problem regarding the variety of food on offer. No cheese. No pasta. Not even salt and pepper. There was soy sauce, though.

Also, it's too expensive yo. Paid like £7 for a bit of cucumber wrapped in seaweed with some rice. What???...
