Don Salvatore serves typical Neapolitan cuisine with fish as the based dish. I had grilled salmon with butter and pizza margherita. The old boat house has a distinct character in it.

The food was good and I didn't pay a hefty price for a healthy meal. Thumbs up for this restaurant. 

The Don Salvatore is located near where the ferry for Capri leaves so it is a great place to stop and eat either before or after your trip the Capri.  More of a trattoria than a true restaurant the Don Salvatore is in an old boathouse.  Most of the dishes feature seafood.  I had a great seafood risotto while my friend had grilled fish (I can’t remember what type of fish it was).  They had an extensive wine list.  The service was a bit slow but they were busy.
