Vodičkova 10, New Town, Czechia
U Sudu is the best of both worlds with a wine bar upstairs and an underground, cave-like labyrinth downstairs. When you walk in, don’t stop on the top level. All that is up here is a normal looking bar. Keep walking until you hit the stairs that descend into one of the coolest places to drink on Earth... It is indeed smoky, but get past that and the place is just mythic.
