Quentino makes good pizza, yes, but it has nothing to do with italian pizza, sorry!
I will also try the one at palermo as I did not eat a real italian pizza in BA untill now and I have tried a lot! The biggest problem is for me the cheese. I spend more than 30 years with eating real italian food from Italy, so I wonder what this is they call Mozarella here. I even tried a "Buffallo Mozarella" which was expensive and a big disapointment, too. But even if it is not an authentic pizza, they make here, I enjoy it! But I have to mention that the ice-cream is even better than the most in Europe.
