Eco Del Mare is a must if you are visiting Vieri Sul Mare.
It was recommended to us by our hotel owner and we ended going there every day for the whole week. My personal favourite was the pistachio and the nutella ice-cream.
The other desserts like tiramisu and nutella tart were also amazing!
I would like to share another experience we had at Eco Del Mare.
We were there on a Sunday evening trying to get a cab back to our apartment. We were just generally asking the waiters at Eco where we could find a taxi. They tried calling up a taxi company, but with no success. Antonio (one of the employees) asked us how many of us were there (we were 7 of us with 3 small kids). He, then, went out of his way and did us a very kind favour and dropped us off at our apartment. It was such a kind gesture!
