Atmosphere - kinda weird, really bad use of space, but I like the overall vibe. They need to get a liquor license and put up a proper bar or put stools on the other side of the table. The 2 huge tables are a colossal waste of space and can make for some weird seating arrangements and insane wait times. We saw a lot of people order take-out and it makes sense.
Service - good. Everyone who works there seems to be genuinely enthusiastic about the food. The entrees come out a little slow but its generally worth it.
Food - good. I think it is crazy but awesome to use wagyu beef and berkshire pork. However, it tends not to show so much in the food because of the tex-mex style tends to hide low and high points with the ingredients. I'm sure if they offered straight up barbecue it would be amazing. All the agua fresca drinks we have had were awesome. I'm a fan of the frito pie and the mac and cheese, but they aren't for everyone. The potato salad was unexpectedly good with those homemade bacon bits.
Other stuff - Call before you go if it's getting late to see if they are open. It's 2012, they should take credit cards.
