Bob, Yes I have considered doing this myself. But, I don't want to work from morning til midnight, or anything similar. Yes, I can probably hire someone to do it for me, but the way I look at it, if I can get a percentage without all the headaches of having to take care of it myself, that is worth a lot. Besides, if the guy who I talked to will do it, he is much more experienced in restaurant management than me, and he actually has people who remember him and would be a bit of a built in following.
The cafe probably would not be serving my normal theater fare. I have a very limited selection at the concession stand currently. We only serve popcorn, soda, candy, and cookies. I could see how serving the same items for a lower price would be a problem. But my regular prices are actually competitive with area restaurants, except for the popcorn (which they don't serve anyway). I still have percaps over $2.00.
It would not be hard to secure the rest of the theater separate from the lobby and restrooms.
