Sacro e Profano1
Why locals love it
This place is located in the middle of the tourist venue, close to Rialto bridge, but it's sort of hidden which is great because there aren't many tourists inside. Visited by locals to have cicchetti and wine but also for lunch or dinner.
Why you should visit it
The food samplings are good but not great, you should not come here expecting a gourmet feast at at this restaurant, but come to have the experience of an authentic osteria hard to find by the lots of tourist traps you can't avoid in the area.
The owners are musicians, and are friendly to chat with.
