My first visit to this venue, I saw Matthew Bourne's "Sleeping Beauty" (a 5 star performance itself). Our seats in the third row of the mezzanine level were excellent. After the show we checked out seats in different locations and didn't find any we preferred enough to justify paying more. The front rows of the grand tier were better, but the back rows I thought were worse than going higher but more forward where we were. Sitting in the orchestra level gives you a different, more head on perspective, but since the rows are not as pitched it would be possible to have your view blocked by someone taller sitting in front of you. For a dance concert, I might sit more to the front of the orchestra to get a better view of the costumes and facial expression, but anything where the music is important I would sit in the front of the grand tier or mezzanine (depending on what my budget allows).
As a newer theater, the Belk does not have some of the elegant touches of an older theater, but it is very comfortable and functional. The seats are comfortable and there is ample leg room. At least on the men's side, there was no problem getting going to the bathroom during the intermission.
I look forward to seeing more shows here.
