My wife and I will be in London for a short stay in May ( late Saturday to early Wednesday ) at the Hilton Metropole in Bayswater. We have made lunch reservation at the Bombay Brasserie (Sun), Hereford Road (Mon) and the Ledbury (Tue). We were looking for late (9:30 PM) and light dinners to complement these. Any suggestions for foodies from Los Angeles? Thank you, in advance, for your input.
