If I am around Zattere and I have time to have something quick to eat, my feet take me directly to Osteria Al Squero, one of my top 5 bacari of Venice.
What makes this place so different from the others? Doubtless the endless excellent and traditional crostini selections and the location.
The bar is very little and has only a few seats inside so the majority of people sit outside on the bank of the canal, enjoying the view of the Church of Saint Trovaso and of the Squero (where gondolas are built or restored) of San Trovaso just in front of the Osteria.
If you arrived around lunch time, then you will find each piece of the counter inside filled with different types of inexpensive crostini (€ 1.50 each), from the fish ones to the meat ones and other types of typical Venetian cicchetti. The best ones are absolutely the one with sarde in saor (sardines cooked with onions and raisin), stockfish, the one with salmon, pink pepper and lemon, the tuna and olive one, and the one with bacon and mushrooms sauce.
There is such a good and quiet atmosphere that you just want to sit outside and enjoying your wine, talking to your friends, watching the boats passing by and the men working at the gondolas in front of you.
