While on family vacation in Florida we had dinner at some sort of cave-man themed restaurant. Our booth sat back in a little personal mini cave. The most memorable part was when our waiter brought the menu. It was a 4 foot tall slab of fake rock that hung from the top edge of the entrance to our cave. I remember feeling a little panicked that we were now walled in. There was no escape from our booth until the waiter returned to take our orders.
