Meh--if you want to go to a taqueria, go to Guadeljara on Park St.
Went there for dinner--not too busy. Free chips with an interesting salsa bar where you could choose your own salsas along with some interesting choices like a tomate de arbol salsa.
The food was good but not great. My companion ate the enchiladas and I got 2 tacos and a gordita. I'd rate the gordita as the best of the bunch. Nice thick tortilla, stuffed with fresh cheese, meats, sour cream, and lettuce, etc. But overall I just felt like the other foods were "ok". The flavors at Guanajuato are much fresher.
