You can never be disappointed with Zizzi and yet this one was quite disappointing, but only because the staff contributed to it. We ordered our food, Salmone Broccoli and Spiedini Pollo with drinks. Our waitress was so miserable that her mood was transferring onto us. She took absolute ages to bring our drinks, with no smile, no nothing! It is really annoying having that kind of service. We were happy with our food and ordered dessert, Chocolate and Strawberry pizza (melting marshmallows, warm chocolate sauce...) sounded delicious, arrived cold, with no melting marshmallows, cold chocolate sauce. We immediately inquired this with our waitress; she gave us funny look, took the dessert back to the kitchen and didn't come back for another 10 minutes. When she eventually came back she said 'sorry, run out of marshmallows, they didn't tell me, do you want to order something else'. I don't know how they could continue with the order without telling us that it will be incomplete. That was all, we asked for the bill and left. She really did ruin a nice evening by having miserable face and attitude. I don't understand people who are working in restaurants and acting this way, she should leave if she is so unhappy there.
