I saw a brilliant show at the Triple Door (Showgirls, narrated by David Schmader), but this review isn't about the show, it's about the Triple Door.
To start the food is prepared by Wild Ginger - enough said.
As opposed to the classic theater layout, the Triple Door is really a collection of booths in a theater. Just about every booth is comfortable spacious and has a great view of the stage.
The staff are very friendly and do a great job not being noticed during the shows.
Overall, a great place and a ton of fun.
