La Viuda Blanca ('The White Widow') is in a quiet and elegant street just off the main tourist route and two doors from the HH Campomanes, one of Madrid's trendiest hotels.

The décor in 'The White Widow' restaurant is all white, including the light-box flooring. On the other side of the bar there's La Viuda Negra ('The Black Widow'), the bar/club – handy for impromptu after-dinner dancing.

Good-looking, mostly shaven-haired waiters (apparently that's for hygiene as well as fashion reasons) wear Hare Krishna-style uniforms and glide around serving up creative but not too fussy dishes and providing some eye-candy for the girls.
