I'm seeing Avenue Q on Monday March 17th.
You can also check out Chicago, Phantom, Rent. And there are 300billion discounts for all these shows which you can get now so dont pay full price.
Also, Splash bar on 17th St has Musical Mondays, where they play videos from Broadway shows. Its cool because there might be a big song from a current blockbuster, and then the next song might be an obscure song from a show from 30 yearse ago. Its free until 10pm.
