Sleuths is always great fun. We just saw it again a few weeks ago in their new location. The venue is much bigger but they had no problem filling all the seats, which I think is a great testiment to the quality of show they put on.
The food was good the first time I went, stone cold this time. However, I was willing to forgive them since the actors did such a great show, especially when one guest asked a question I am absolutely certain they have never heard before. After a rather long pause, the actor who had to answer the question came up with the perfect answer. The whole crowd broke out cheering at the skill (and ability to stay in character!) necessary to handle audience questions.
Go. It's a fabulous evening.
