Try Giorgio Locatelli at The Churchill for interesting Italian food in very nice surroundings.

Little Italy in Soho is loud and lively with good food - remember my girlfriend dancing on the table there one night a few years back, when she was wild.

Marousch in Beachamp Place is top-notch Lebanese food and a very interesting clientele (round corner from Harrods).

Les Trois Garcons in Shoreditch is the most eccentrically designed interior in London and the food passable if you like French cuisine.
