I visited the Canaletto Ristorante Veneto with four co-workers for lunch during the HIMSS conference. It's a short walk away from the Sands Expo Convention Center in the Venetian's Grand Canal shops. They were able to immediately seat the five of us. The location inside the plaza with its realistic sky ceiling is great for people-watching, but the food was underwhelming for the price. I ordered a calzone because at $20 it was one of the least expensive items on the menu. It was the size of my head, but I didn't taste any of the ham that was supposed to be in it. The mozzarella and ricotta were delicious. It took between 75-90 minutes from being seated to order, eat, and tab out, which I learned was pretty standard for Vegas. The food at Canaletto was good as well as the service, even if it was slow, but you're paying for the premium location. There are other places in the Venetian with better food for the value in my opinion.
