First time in Venice next Wednesday, seeking recommendation for delicious seafood restaurant preferably in Castello area. We are a family of four with two teenagers (non fussy). We tried to book dinner at Rick Steve's favourite, Oteria alle Testiere but no availability unfortunately. Thanks very much!
For seafood, our go to place in Venice is In the Rialto Bridge area. The name is Trattoria Da Marco Valla Fava on Calle Stagneri. It is definitely pricy so you might want to do lunch there rather than dinner. Some of the best sea food ever!! Try to eat inside rather than outside. The place has been around at least 50 years so they must be doing it right.
Also in the Rialto area (but on the other side of the Grand Canal) when walking to Piazzale Roma is an out of the way place named Pane Vino e San Daniele on Calle Dei Boteri. Not a seafood place per se, but definitely a local place, good food, good house wine, and not expensive at all.
