We got fantastic deals on Travelzoo, something like $15 for $45 tickets and it was totally worth it and a lot of fun.
I was a little worried because we had been given seats in the second last row and more to the right than the center but we could see everything on stage perfectly well.
The costumes, the energy, the interactiveness and the humor all made for good entertainment. They take a lot of mileage from the 'cutesy Japanese' stuff but it didn't really get annoying.
My only gripe was for how freezing cold it was in the hall.
