I actually prefer this place to the bigger Thomas and Mack next door.
I've been here for multiple basketball and volleyball games, as well as the NBA Summer League. It's got great sight lines for both sports, but offers an intimacy that's not available in a bigger building. And if you're an NBA junkie, this is the best place in the world for two weeks in July. You'll run into uber-agents, uber-journalists, groupies, hangers-on... oh, and the players too. Sitting just behind Mark Cuban for a Mavs game was an experience itself.
Yes the drinks and concessions are overpriced, but that's to be expected at any major venue nowadays. A great little gym with all the benefits of a bigger space.
