This place is located next to the channel, probably one of the nicest place in Berlin.
Pizza is good and price is quite fair. From €6-11. Beers from €3.50-5.
They have outside tables but is usually packed, so plan on waiting for a while or come off peak hours.
Not only pizza but also Italian food.
Il Casolare has two “sisters”: Il Ritrovo in Friedrichshain (Gabriel-Max-Str. 2) and I Due Forni in Prenzlauer Berg (Schönhauser Allee 12).
