Like others have mentioned, this is a very interactive shows that asks you, as a guest of "Tony Soprano (aka Tony Baritone)" enjoy yourself both by watching the entertaining play they put on as well as getting up and dancing. If you're lucky (or unlucky in some cases) they will even pull you behind the stage and while still in character, ask you to become a politician on the take from Tony or possibly become a member of the familia itself.
I especially enjoy that comments from the surrounding cast as they wander around and speak with you or just generally interact with the crowd. Whether or not you know about the TV show, enough is explained or shown in the introduction and play to give you enough of a gist as to what is happening.
The food is okay for some, it was a little light for me. I am used to the Tournament of Kings game hen dinner, and this pasta was not necessarily my style. Drinks are expensive and water does cost $3.00 a bottle, so nothing is free.
The value of the show is well worth it if you do like the Soprano's or interactive theater, but if you just want to sit back and watch a show, I would not recommend this "Last Supper."
