We went there while in Dallas about 6 months ago...they didn't even have the buffet anymore. That was all we were looking forward to.
I know when we order delivery it is always very expensive and the pizzas are much smaller than when I used to get them as a child.
Mazzio's has the best delivery, and the best ranch dressing to go with it. If you have one in Raleigh, I suggest testing it out!
