We had a nice lunch here, although experienced some slightly aggressive behaviour from one of the waitresses. We arrived around 13:30 and queued for 30 mins or so for our table, which was no issue. The staff were initially friendly and very kindly adapted the bruschetta to be vegetarian for us, which was much appreciated. We had the spinach & ricotta ravioli (sauce was really delicious) and spaghetti carbonara, which we enjoyed. The issues started when we asked for the bill. We were waiting some time for this, so politely asked for it in Italian, but 20 mins later there was still no sign of the bill & we wanted to get on with our day. Our waitress walked past making eye contact with us, so we said “excuse me” in Italian. She literally angrily shouted something at us as she walked past, then proceeded to actively ignore us for a very long time. We ended up asking another waitress for the bill. Then as we left we encountered our original waitress and stepped aside to let her past. She angrily muttered something and rolled her eyes at us. I really don’t know what we did to make her so mad at us, particularly as originally she was very polite. It was not a very nice experience and now we do not want to return. Hopefully this is just an isolated incident as doesn’t seem like this has happened to others. Still not something I have ever experienced before and we found this quite unprofessional.
