Canteen, Bar, Night spots
San Luis Potosí #28, Col. Roma Norte. 06700, Roma
What it is. A cantina and night spot on San Luis Potosí in Roma Norte —the old-school end of the neighbourhood's nightlife, where the room matters more than the cocktail list. Expect a long bar, cheap drinks, loud conversation and music rather than a designed venue.
Check the days first. The posted hours here are unusual: open in the evening from Monday to Thursday and on Saturday, from 20:00 until 02:00 or 03:00, and closed on Friday and Sunday. That is the reverse of what anyone expects, so confirm by phone or on the door before planning a Friday night around it.
Practical notes. Cash is the safe assumption in cantinas of this kind. Roma Norte is compact and walkable, with dozens of bars within the same few blocks, so it is easy to move on; metro Insurgentes and Hospital General and the Insurgentes Metrobús are all a few minutes away. Take a ride app home rather than a street taxi late at night.
