One Twenty One Two Restaurant

One Twenty One Two is The Royal Horseguards Hotel's restaurant, its name taken from 1212 Whitehall, the original telephone number of Scotland Yard, whose former grounds lie close to the hotel. The menu draws on modern British cuisine, served within a dining room set inside the hotel's Victorian building on Whitehall Court, overlooking the River Thames.

The restaurant sits alongside the Equus Bar and The Green Parlour as part of the hotel's dining offer, and its name and setting are used to connect the food directly to the building's history as a site linked to London's law enforcement and diplomatic past. It is positioned as the hotel's principal dinner venue rather than its bar or afternoon tea room.
