Sat in 110 for last season's Bulls-Bobcats game-row 11. Pretty cool seeing Derrick Rose so close and in person. Really the only reason I went to the game (I'm from Chicago).
The first few rows are numbered A1-A5 and then the rows go from A to T if I recall correctly.
You're behind the goal which is not nearly as good as the sidelines in any NBA arena.
But you can find cheap tickets in the lower level of TWCA and there isn't a bad seat in the lower level.
Highly recommended.
