Mezcal and Munchies
This is, kinda, your prototypical Oaxacan mezcaleria. They have an impressive selection of mezcal, including a healthy selection of their own product all of it very very good. You've got folks who are happy to either leave you to your own devices, help you just enough for you to hurt yourself, or spend hours chatting with you about the specifics of the mezcal you're drinking, their own favorites, and whatnot.
There's also mezcal-appropriate food, i.e., nothing fancy, but all of it designed to help cut the alcohol (oh those fries!).
There's also a roof-top which can get crowded, and the small high-top tables indoors perfect to just spend a few hours of the crazy afternoon heat.
In short, well worth going to!
