Pre-theater, you could try Cafe Edison, in the Edison Hotel. I'm not sure where it is exactly, but I think it's 47th and something. It's a classic, old-school New York Jewish coffee shop with fantastic chopped liver, etc. Not fine dining, but a true institution where (I'm told) lots of actors and playwrights go or used to go. Anyone else like Pam's Real Thai? I've been once and swooned. Again, I'm shaky on the address, but it's definitely in that area. Have fun!
