Also, not too far from the Duomo is the actual site of the last supper painting. It's quite breathtaking to be standing there looking at it in person. I always thought it was painted on canvas, but when I went to view it I realized it was actually painted on the wall inside a building. It's worth the trip. There is also a great restuarant near there called La Sassino. Translation...I assasinate you with food!
