Every time I come here, I think to myself "Why don't I eat here every day?"
Honestly my only quip with this place is that if you come after like 6:30pm it just gets really cramped, and we ended up having to stand outside on the street for roughly 20 minutes on a chilly night - it was a Tuesday and we came during Happy Hour, so the bar area was packed. But really, the fact that it's too popular is probably the only thing wrong with this place, and is that really a bad thing?
Tacos look small at first glance but are extremely filling, service is very fast and efficient, the chips and salsa keep flowing; I've never had a bad food/service experience here.
And get the Choco Taco. It's like what you would get from an ice cream truck, only x500 times better.
