My dh had one of their pizzas at the RC in Virginia. Now, it's been a while, so this might not be correct, and maybe it's done differently in FL. BUt, he thinks the pizza was a single serving size. He doesn't think he had anything left over. He's guessing 4-6 smaller slices.
Hope this helps...I wish I could be more accurate, but it's the best we can do.
I think it is an individual pizza that is cut smaller. My guess is that it is about an 8" pizza. Occasionally they are cut into squares instead of slices.
