The restaurant Dogana is located very close to the Duomo, on one of the streets in the area. We stopped there because we were approached by one of the waiters. However, at the same time a waiter from another "rival" restaurant began trying to convince us to go to there. They were even arguing with each other. It was a very bizarre scene, but as it was dinner time and we thought it looked good, we followed the waiter and we ended up having dinner there. The restaurant is quite nice, with an enclosed terrace and quite a small dining room inside.
