This long-standing Mayfair spot pretty much does what it says on the tin: it's an icy bar. It's kept at -5C, with visitors given thermal boots and jackets to keep the cold at bay. Each session lasts 40 minutes, and should be booked in advance.
Drinks – served in tumblers made of ice – include a stairway to heaven (Pommery Champagne, Aperol and grapefruit bitters) and a living on a prayer (Absolut Citron, pink grapefruit liqueur, cranberry juice, lemon juice and orange bitters).
There's an upstairs restaurant and lounge, too. The food menu here features dishes such as ham hock ballotine, rabbit pie, a house burger, flat iron steak and a chicken, red wine and bacon casserole with a bourguignon garnish and garlic mash. Desserts include an orange panna cotta with meringue, orange candy and hazelnuts, as well as carrot cake served with edible soil and mascarpone cream.
