I've seen it 18 times I think, about a dozen of those at the Shubert. The most interesting seats are aisle seats in the Orchestra (or as close to the aisles as you can get), because of the actors making their entrances and exits, as well as a bit of a fun gimmick event that happens down there. Mezzanine is all right if you just want a view, but I wouldn't recommend the balcony.
