La Puerta Roja

A world of fun beyond the red door
Noteworthy for: The drinks are cheap and the crowd up-for-it. This is somewhere cool locals come to meet the keen and curious from around the world.

Word to the wise: Happy hour is until 10pm.
You may not stumble upon this accidentally, but once you do, it will become a firm favourite. Behind an unmarked red door, ring the bell, and enter up a winding staircase to one of San Telmo's best no-nonsense bars. It attracts a mix of travellers, porteños and expats, all of whom come to get trashed as the night descends into a wild party around the leather booths.

Prop up the bar, and get chatting to the fantastically fun-loving and friendly managers, who are a source of knowledge about the city. This place is not for the weak-livered, though.
