They're back! I was so sad when they closed it last year.
Taco de adobada (spicy pork) is the best one there. It's spicy, juicy and rich in flavors. Drools*. When you order, they'll ask if you want everything on it (toppings & sauces), say yes!
Avoid long line by going in the day time, it's super packed after midnight but it's also the best time to eat when you're drunk :)
