We had dinner at Kaos in mid-July and the pizza was fantastic. Beautiful setting in old Ortigia. Very affordable with pizzas ranging from 4 to 8 Euros. Wait staff was a bit hurries so it took a couple of tries to get a second round of beers. Good spot if you are traveling with kids.
The restaurant offers its customers the chance to enjoy its products in front of the magnificent scenery of the Cathedral of Syracuse without noise of vehicles or scooter thanks to the pedestrian that allows children to be able to run around safely while parents are sitting comfortably at table.
