Rosi is the main restaurant inside The Beaumont in Mayfair, led by top chef Lisa Goodwin-Allen (who also runs Northcote). The restaurant here is all about British dining, with classics like pork pies and suet pudding on the menu. There's also a big focus on tableside theatre, with a fair bit of flambeeing and the build-your-own sundae is always a big draw.
