Real Cantonese food and very reasonable - go to Leicester Sq, north side, there's a small street running up into China town (leicester st) - anyway there's a NCP car park on the west side. Opposite there is a super restaurant, Poons (no relation of the Covent Garden Poons or the Poons 100 yards away on Lisle Street.
Plenty in that area of town from the National Gallery, St James (there's a Wren church there that does brass rubbings), St James (and palace), Fortnum and Masons (the Fountain room for tea), Dunhill etc etc, Burlington Arcade; Whitehall isnt that far away - drop into the Savoy to see it after the reconstruction.........
