St. Mark's Square is a must. Feeding pigeons is fun. Be sure to spend some money on the Bell Tower. Looking down from the bell tower at the Grand Canal and Lido Island, wow, wow, beautiful. For those who want to enter the church, remember to deposit their shoulder bags free of charge next to them. The Governor's Palace and Sighing Bridge are actually beside the square, which is very convenient. We had dinner in the evening and unfortunately met the black shop in Venice. The regular Italian restaurant serves the dishes according to the menu. The dishes in this restaurant are more than 10 times the weight of the menu. I didn't realize for a moment that it was a pit. After eating a few pieces, he realized that he might have been pitted and asked them how much it cost. He gave them a bill of more than 231 euros (30 or 40 euros for three people in other restaurants). I threatened to call the police, and after many theories, they were reduced to 100 Euros. Remember not to go to this black shop. The name of the restaurant on the Google map and the dining board is Riovenice, and the entrance sign is Ristorante.
