Absolut Ice Bar

From Frikipedia

The Absolut Ice Bar is located near Piccadilly Circus in London.

It is a bar constructed entirely of ice, where punters can book a 45 minute session to freeze their bollocks off and drink expensive vodka cocktails from glasses made of ice (ices?).

Entry is a cheery £12, so long as you go during unsociable hours, which entitles you to a natty thermal poncho thingie and a free drink. Further drinks cost £6, but are essential. The ponchos ensure that any photos you take of your group will turn out to look like the day you joined some really odd Eskimo cult. You sadly can't keep your poncho, however, and this is rudely stripped from your person as soon as you exit by a member of staff, making you feel violated in some way.

The staff have to stay in the freezing environment for longer, so they are entitled to hats.
