This sloppy gem of a loft is part metro stop, part college-dorm commons, part debating society, and part pulquería. It's run by 1950s national lightweight boxing champion and folk hero Epiphanio "Pifas" Leyva, and serves beer and pulque (a drink made with the fermented sap of one type of agave plant) to a young, intellectual crowd that loves to sing and dance to the excellent jukebox of punk and local guacapunk (Mexican ska) classics. If you want a rowdy afternoon (the bar is usually closed by 11, and always closed on Sunday), this is the place. Note that it's technically in the Doctores neighborhood, but borders Colonia Roma.
