This place has horrible service, even by Italian standards! We were walking back from Capuchin Crypt and stopped by to get some take away granita because it was so hot. You need to pay at the counter before being served, so I lined up and waited. When I was next to be served, the cashier ignored me, spoke to another colleague, so I waited some more.. She finally took my order and payment after a couple mins of me standing awkwardly at the counter. I then took my receipt to the ice cream/granita counter only to be informed 2 of the 3 flavours were unavailable. The size of the cups were those super tiny white plastic cups, and that cost me 3 euros.. I could get a bigger size for half the price from the place a couple shops down!
