You take the bus to the blue grotto and it is one of the restaurants close by. If you want a sunbed (please note that the place is tight and all sunbeds are very close to each others) please reserve one in advance as a restaurant reservation does not guarantee you one. Food is simple, good and not expensive, wine card non existent. Overall ok but not great compared to other places one can eat on the island. More of a beach restaurant type (no beach though but access to water alongside cliff).
