This guys are simply the best fish restaurant on all Veneto (or the World IMO)
This restaurant has excellent service and the food is magnificent, starting by the courtesy homemade mayonnaise to every single dish they serve. Their trick is freshness, they used to do almost daily trips down to Venice (don't know where exactly) to purchase the freshest fish possible, this obviously increases the price and limits the availability of some products but is worth every penny.
Reservations are almost mandatory due to the great demand, but the times that I have gone without they have always found place to accommodate us (last time i discovered a "hidden room" that holds only 4 tables)
You cant go wrong with anything here. I highly recommend the "Cold and Hot Antipasti" and the Grilliata (Fish BBQ)
