It's a restaurant that has caused Honeymooners to go 5-hours out of their way to dine here: the  Hotel Ristorante Grotta Palazzese  in Polignano a Mare, Italy is home to one of the world's most unique restaurants, which is built inside a cave on the edge of the Adriatic Sea.


From your table you can see and hear the waves crashing from the sea below.


It boasts 5-star food, the smell of the sea and possibly one of the greatest dining experiences you'll ever have.
