I had heard about the show before and although it wasn't my first choice (we passed by 'Avenue Q' and 'Billy Elliott' first), they were having a lottery for the front row seats and as luck would have it, we won!
Winning is always exciting but I can't say the show was all that great. The jokes were a little corny. The music and songs were just so-so and I was surprised it won the 'Best Musical' award for 2008. Plenty of double-entendres.
But you could tell that the production, the set, and the costumes were very expensive. Though the house was packed that night it was obvious the show was losing money and would be closing in January. Spamalot is much better but when we watched it we actually had no seats and had to stand during the show for roughly the same price as our lottery tickets here.
Actually, here's a link to a more comprehensive review in the New York Times (which says our tickets were worth $450 each!):

But despite everything, I really must say, the lottery was definitely worth it! For $27 you get the best seats in the house and I really kept going on and on about how lucky we were because it was a full house from orchestra to both balconies. This probably will be my last Broadway play of the year. Now if only I can get my good luck to work on 'Wicked'.
