Feng Sushi has a handful of sustainability certifications to its name, and its carefully sourced seasonal menu aims to showcase the best of British seafood in attractively presented Japanese cooking. The menu is a long one, taking in cooked dishes - noodle soups, curries, tempura - in addition to sushi and sashimi, where inside out rolls feature prominently. Seasonal specials add variety, and there's also a selection of sushi made using brown rice rather than the standard white. Boxes and platters (some of them very large) cater for the takeaway crowd. Prices are a bit on the high side.
