El Diablito
Identifiable by the leering devil on the sign, El Diablito is one of the only divey places left in Lastarria/Bellas Artes, whose decor sports spurs, stirrups, and other metal items. If you want to see what this area felt like about 10 years ago, before gentrification, this is a good spot to try. It's popular for drinks after work or late at night.
