I'm not typically a fan of stuff your face buffets. They are too crowded and I feel like a cow in a herd waiting for the tough to be filled, but Godfather's is one exception. THey have a super cheap buffet...we're taking $4 for lunch, and you get pizza, salad if you want and some little dessert pizzas.
They also have a basketball hoop above the register....score a hoop and you score a free buffet. They've also got a punch card where you can earn a free buffet. I HIGHLY recommend Godfathers.
