I'm surprised to see some of the criticism that people are proffering for Cactus. I went there for the first time this past weekend, and all things considered, had a fantastic experience. The wait was admittedly pretty bad -- but it was a Saturday night at 7pm, and the Attic next door served as an excellent waiting lobby.
I was very pleased to see the breadth and variety offered on the menu. There are a lot of Latin influences, but given the Native American and Spanish-themed dishes, this is not just some "Mexican restaurant." The food is creative in both taste and presentation, the wait staff was friendly and helpful, and the atmosphere is boisterous and exciting.
Oh yeah, and this place has far and away THE best nachos I've ever had in a restaurant.
