This was me and my girlfriend's absolute favourite place during our stay in Vernazza.
The staff was friendly, and the meny was good. However, The Ananasso Bar's strength is the location. It is situated in the middle of the square, just by the harbour, so one can enjoy their breakfast or maybe evening drinks here with a great ocean view.
My favourite drink here was the Bellini, made from fresh peaches.
I'd recommend this place to anyone visiting.
