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. Drinks - served in tumblers made of ice - feature mojitos, kir royales, jaliscos and a Double Vision - made with Absolut Blue vodka, apple purée, passion fruit juice and lemon juice. Each session lasts 40 minutes, and should be booked in advance.
There's an upstairs restaurant and lounge, too. The food menu here features British dishes including charcuterie boards, chicken wings, pork belly with cornbread, burgers, flat iron steaks and chicken and wild mushroom terrine served with brioche. The cocktails list ranges from spritzers and negronis to punch bowls and after dinner specials.
