It looks very little like the real colosseum but I am betting it is much more entertaining. If not for the outrageous drink prices, I would have only good things to say about this venue. Over the years, I have seen several concerts, comedians etc. Not a bad seat in the place. You do pay through the nose for those good seats, but I prefer to get good seats to less shows than crappy seats to many shows.
My husband saw The Who here and said it was one of the best nights of his life excluding the first night we did the dirty. I am still angling for Mariah and Elton John tickets. Of the shows I've seen, all are great but if I had to pick one, Rod Stewart all the way. I'm not sure how a 70+ year old can move like that or make me blush but Rod's still got it!
