My daughter and I ate here three times during this year's Comicon and had great experiences each time. The serving staff wasn't quite as attentive as I might have liked, but it was during an extraordinarily busy time.The burgers and sweet potato fries we had were super tasty, and they do make a very fine margarita.
This would be five stars had the waitstaff been a bit more on top of things (maybe an extra hand or two during high volume rushes or conventions at the Hyatt?), and the prices been a bit more reasonable - $25 for two burgers, two fries, and two sodas is a bit steep.
