Pótkulcs is a hidden gem in the nightlife of Budapest. Only the most watchful discover this pub and that’s why it has been able to preserve its unique multicultural atmosphere that makes it special. The dilapidated brick walls of Csengery utca do not bode well, but once you enter, you'll find a pleasant garden outside and comfortable armchairs, firm tables, table soccermusicians and drinks at a good price inside.
