Almost as good as the original (OK, not sure if this is the original location or Phoenix is but 16th street is original for me). I'm not sure what it is about that location... The food is a tad better, in my opinion, but this location is much closer when I'm at my office.
Food: I usually get the el pastor burrito... It's delicious. All the tacos are good and I haven't had any complaints on anything from the numerous people I've brought here. I always fill up on chips and salsa because there are SO MANY - my favorites are the cilantro and chipotle salsas and guacamole; tip: mix the chipotle salsa with a spicy one for a kick because it's not at all spicy!
Service: usually good. The credit card machine was out once... Not a huge issue for us or anyone I saw walk in but would have been disappointed if we didn't have cash.
My only complaint is that they serve the food in baskets and I would prefer plates (I think this is new... I can't remember) but I can work around that if I must... And I haven't asked for a plate, which I could also do
