This isn't the standard generic Americanized Mexican food. You'll probably figure that out once you see beef tongue tacos or goat stew on the menu. While the interior/ambiance is a little rough/lacking, if you're looking for something more authentic (I guess it depends on your definition/version of authentic) you should be in luck. There's lots of interesting menu choices that sound fantastic.
Good service and parking lot in back of building.
I had the Cubana torta and it was delicious. The salsa was good as it had a bit of heat. Unremarkable guacamole and tortilla chips.
I want to return to try out the tacos and some of the specialties.
