Taqueria with some Guadalajara specialties. Clean and bright interior. Very friendly counter service. Their al pastor tacos are great, and so are their Tortas Ahogadas. Well marinated and flavorful, with good spice choices. The meat seemed of good quality (no gristly bits).
They seem to be making things semi from scratch in the back, and only have one person at the front, so it's not a place you can just quickly walk in and out.
No liquor license, they have a decent selection of Jarritos.
Definitely worth a stop if you are in the area.
