I am slightly confused by the reviews for Pizza Bellino, as they range from thrilled to enraged. Pizza Bellino is one of the closer pizza places to my apartment, but I just made it here recently. I stopped in because I was starving, and they sell single slices for $2. I got a great slice of cheese pizza! One slice was enough for a small meal, and the sauce is very nicely spiced. The cheese quality is good too.
The service is pretty fast when you eat in, unlike Aiello's and Mineo's. I have always had good customer service here as well. There are crazy good lunch specials, and they always have deals in the Squirrel Hill Pennysaver.
As one of the only places that delivers in Squirrel Hill, I can imagine it can be pretty slow and tense. I would stick to eat-in.
Good for a quick slice of pizza!
