We had a couple dinner theaters near where I lived in Chicago. One was called Candlelight Theater. The dining room was round and had a balcony, the stage was in the center but the floor opened up and the stage actually rose up. It was very cool and a very popular prom dinner destination.
Our local grocery store would occasionally have a type of scratch off game that you could win tickets to one of several in the Chicago area. I won tickets twice, once to a theater downtown Chicago for a play and another time to see Suzanne Sommers and Rich Little. That stage was also cool, it was also round but it rotated very slowly so everyone could see the performance.
Yea, I miss having those things close by. I'm sad my kids haven't experienced stuff like this, it's generally very expensive. Nothing like a live performance.
