My recommendation: be as creative as you can be ;)
As soon as you walk in you are greated with such a warm welcome that you have to stop and think if you know the cashier personally lol. The whole crew has an upbeat attitude and everyone is ready to help you with any question or request you may have.
It's a buffet for $5 so you can't expect gourmet food, but they try. If they don't have a pizza you like sitting out already then don't hesitate to have them custom make you one. I hear they have some pretty unusual ingredients too lol.
My favorite thing at Cici's is their cinnimon rolls. I probably eat more of those than I do pizza.
Overall, it's a friendly environment with decent food. Cici's is a great place for the family.
