Great atmosphere. The seating layout are well-designed so even if you're in the upper sections, you still have a nice view of the game against the Nets. Tickets were courtesy of my Bay Area relatives so I have no idea if it's expensive or not. For the meals inside the arena, the chicken wings were good and addicting, so was the etouffe. Of course, it's a little pricier than the outside the building but it's filling nonetheless.
Getting there was pretty straightforward via BART from Dublin/Pleasanton station.
