As one of London's most celebrated society restaurants since the 1920s, Quaglino's has seen some famous feet descend its statement staircase. It was revived by Terence Conran in the power-dining 90s, and is now part of the D&D London stable. Following a multimillion-pound refurbishment in 2014, the impressive room now holds up to 500 diners in total. For smaller groups, there are two striking private rooms which overlook the main space. Like the clientele, the food is international with a luxury twist. Expect the likes of shellfish bisque, followed by its signature lobster, langoustine and crab cocktail.
