Saw Cirque's "ZARKANA" last week at Radio City. If you are a big Cirque fan, see it. But I would suggest skipping it and do Broadway shows. Not one of their best.
If you want to see "Book of Mormon" take a day and do standing room. I thought the show was a bit overrated but it is worth the standing room price.
How to Succeed with Daniel Radcliffe (I didn't know Harry Potter was in the show!) was very good and if the show is up when you are here, it is worth seeing.
If you want to try out something new, "Death Takes a Holiday" is at the Laura Pels theater. I plan to see it this week.
I say definetly see Spiderman" It isn't the greatest but see it...just because! The sets and visuals are pretty spectacular.
