A no-strings attached gem, the Weinerei offers unlimited wine, juice, and a meal for a one Euro fee (plus a donation on exit) in central Berlin.
The cafe itself is small, packed with locals and the wine isn't bad either!
A must-visit for budget travellers with a penchant for good wine, conversation and value.

Updates
I was there late October and the charge for the glass is two euro. They finish serving food early in the evening, so beware of that.
Is this your business?
