They very recently changed their pizza recipe. The new kind is less greasy, but it doesn't taste as good.
Also, I tried one of their buffalo chicken salads for the first time. Pittsburgh has a unique style of salad which includes french fries and breaded chicken- a lot of restaurants do this- and that is what Papa Da Vinci's tried to emulate... They do a truly horrible job of it, though. The lettuce was literally dripping wet, as if someone just rinsed off a bunch of lettuce and stuck it in the container without drying it. On top of that, they had shredded bits of chicken meat (no breading) and then some other toppings, including cheese and some "buffalo fries" (flat fries cut sort of like thick potato chips). It was hard to choke it down due to the sogginess. The fries were disgusting because many of them were soaked through. It was just... You know, I don't even want to talk about it anymore. It was bad, bad, bad, bad, bad.
I'll probably still order from here occasionally since they're dirt cheap, but I'm definitely never getting a salad again!
