Been very happy with first two visits. The chicken is surprisingly moist and flavorful for a taqueria, and I like the endless combination aspect of the build-your-own here. Ten different salsas, some of which are more for flavor than heat (e.g. #2, tomatillo based, which adds a nice acidic taste). The chips and guac are very good, my 4-year-old was a fan...
Friends with the chef, here are a few things he has told me about the "bad-ass taqueria":
Big lunch crowd from the nearby high school, also not much takeout in the area so picking up more by word of mouth each day.
Breakfast tacos off-menu when they first open (haven't tried myself yet but it was his plan).
Some specials in the after-school hours too.
Salsas are all bottled and available for separate purchase.
You can sample a salsa or two if you are undecided (as I have been both times).
There's no seating, just a few standup counters from reclaimed wood. Yet I like the vibe of hanging out there, vinyl records spinning and a steady stream of people. I personally wish John would deviate from his "no Sundays" rule and have this place open. Probably not enough business to support it though.
