A typical tip in Italy is surprisingly less than most might expect. On a 20 EURO bill, most people will leave €1, €2 if you really liked the service. The tip is not correspondent to the percentage of the bill, but rather a reasonable amount based on how happy you are when paying that bill. Taxes are included in the prices, and on a 100 EURO meal, a normal tip could range anywhere from €5 to €20. It's really up to you, your budget and how well you enjoyed your food and service.
