You may not quite need a diamond as big as the Ritz to drink at this art-deco marvel, but it might help. All camphor wood, illuminated Lalique glass, golden-ceiling domes and stunning cocktails, the bar is a gem. Unlike in some other parts of the Ritz, dress code here is smart casual (this laxity does not extend to trainers).
Caviar, oysters, and more substantial classics such as tuna niçoise and oxtail shepherd's pie are available between 11.30am and 10.30pm (£36 to £375).
