We dined here on opening night as well. Overall nice interior and people were relatively friendly. The wait staff struggled a bit (most likely first time nervousness) but you can tell they are not used to carrying trays yet.
Food was excellent. I did receive a cup of salsa all over my pants from a server attempting to carry the tray, but after that the food was really good (short rib).
The manager did come by after the salsa spill and tell us he'd bring margaritas, but I was a little surprised to see it charged on our bill. Drinks are delicious but a little smaller than a traditional Mexican restaurant.
All in all, good to try and really good food, but I think they might have some growing pains until they get things rolling.
