The Bloomsbury Club Bar
This sultry Art Deco-style bar takes inspiration from the Bloomsbury Set, a group of influential writers that hung out together in this part of town in the early 20th century. The cocktails are named after the group's best-known authors including Virginia Woolf and E. M. Forster and the cozy wood-paneled space has the feel of a private library. For an atmospheric aperitif, head to the vine-clad terrace which is lit by twinkly fairy lights and lanterns.
Hoxton Holborn Lobby Bar

Bar snacks including truffle fries and baby back ribs are served from the neighboring restaurant's open kitchen.

Keep things simple with an authentic gin and vermouth combo or pick a quirky variation like a white truffle martini.
