Came here in the summer with no reservations and they were able to accommodate our group of 8! Everyone was very kind and willing to help us understand the menu and the tacos they serve. There was only one bad apple but she might've just tolerated my loud group enough to where she didn't care anymore.
In terms of food, we knew this location was the reported the best of the chain restaurants. I ordered the braised rib tacos and pulpo (octopus). Both were very flavourful and easy to fill you up! The pulpo is the most worth it in my opinion, my taco looked like an entree as I ate the filling with a fork! Only issue is that is is very spicy to the mild mouth (me), I'm sure it burned a hole in my stomach but I would do it again!
