Viva Tequila!
This is the place to drink in history and get inebriated on knowledge. They have two prices for admission- basic admission to go look around, or a tour with samples. My advice is obvious- spring for the tasting. A private semi-English speaking guide came by with a tray of margaritas and tequila mojitos. This is how all museum tours should start.
The guide led upstairs to the exhibit on the different types of agave plants, and where they come from and how they have different characteristics. Then they take you to the process where they carve the agaves into pinas, and mash em up, ferment them, distill, then age them. They have a sample pot still that looks like it'd still work. The coolest part of the exhibit is where they have a giant wall of tequila and mezcal, with hundreds of brands shown. Approximately 60% of all tequilas and mezcals made are represented here, but they're not all served. They have mezcal bottles with worms, scorpions, and even snakes in their bottles. Odelay! On they way out, they teach you about Tequila and music, with the advent of the mariachi band. Viva!
Once the tour has ended, they take you up to the rooftop bar, where they poured shots (champagne flutes) of a silver, reposado, and an anejo. Then a joven mezcal, and an aged mezcal. (seven drinks total!) As we sampled, they were more than happy to offer refills of the favorites, just to make sure that we had a good taste for them.
They served up some bar food, greasy asada nachos. They had clean restrooms.
There's also a gift shop on premises that sells a bunch of cool tequila stuff- shot glasses, bottles of cool tequilas, magnets, etc. The selection of tequilas for sale scaled towards the high end, with a carefully curated inventory.
The downstairs patio served up drinks, with papel picado flags everywhere, looking out on Girabaldi Square, a famous mariachi and tequila place. It's worth stopping in for a drink and learning about this important beverage.
