Khew, 43 South Molton Street, W1 (020 7408 2236) £40. The area was crying out for a good restaurant and figure-conscious shoppers are ideal bait for the crustacea, sashimi and ceviche at the Raw Bar on the ground floor. Downstairs in a cramped, awkward dining room, key flavourings such as soy, ginger, chilli, garlic and sugar can hit strident, clashing notes.
