I've been at the Thomas & Mack Center for various events since 2000: a high school graduation, concerts, college basketball games and NBA Summer League games. Each time has been a good experience. Friendly staff, not a bad seat in the house in my opinion. Concessions is generally the same as other arenas I've been to: overpriced and processed fries and burgers that do the job.
Taking Lyft and Uber is a breeze with the drop-off and pick-up area at the main entrance.
Overall, 4 stars!
