That being said, it was very nice to walk through.
The market by the Rialto is worth a look, but it closes early. It is sort of like a flea market, and everything is sold in this area. We had a vaporetto pass and used that to get from one side of the canal to the other. (There was no way we could get over the Rialto bridge with the scooter.)
Everything has gotten VERY expensive. It is very easy to spend 150USD per person for a sit-down meal. There are less expensive places to eat, but plan on even those costing 40-50USD for a simple pasta dish.
