While it's not great, it's far from the worst.
Dollar for dollar, it's only slightly below Dominoes. Caesar's used to be better, too, before they restructured their business model into the $5 thing. Remember their Bigfoot pizza? Not bad. It was a big rectangle, and I liked that it had slices in the middle that were square with no crust.
As far as chains... I'll give the honor of worst to Numero Uno (except CiCi's, but they suck so bad they don't even count).
You know who else is good? Shakey's.
Going off on a bit of a tangent here, but the concept of Show Biz Pizza/Chuck E. Cheese is solid, I think. Pizza, games, entertainment. They just suck at it. Shakey's is like Chuck E. Cheese, but good.
Holy God, CiCi's is bad. That place seriously fucking sucks.
