if you have a car, ask the hotel for directions to CiCi's Pizza, there is one located in the shopping centers on that little strip on 535, less than 1 mile from the hotel. Its an all you can eat pizza buffet for around 4 bux a person. it also includes a salad bar, a pasta dish & dessert pizza. your teens could really fill up there!
There is also Pizzaria Uno & TGI Fridays in the Crossroads shopping center (& Chili's too, I think) The McDonalds in the crossroads does have a $1 menu, you just have to ask whats on it because its not listed on the drive thru menu. I know for certain they have spicy chicken sandwiches & small fries for $1 each. There is a Burger King also just down from McDonalds going twards Winn Dixie. I also think there is a Taco Bell in the Crossroads area too.
