The student rush sells out quick I hear, so you're better off with TDF, the seating is pretty good, I highly recommend the show. It plays at the world stage theater.

Just to clarify, TDF and TKTS are two different things, and I think jbm2 meant TKTS. For those who don't know, TDF is a members only website run by the Theatre Development Fund. They also run the open to the public TKTS booths. But they are two different things.
Bare tickets are frequently available on the TDF site, AND at the TKTS booth. If you are not a member of TDF, try your luck at the TKTS booth.
