Great restaurant with sea view, especially crowded during lunch on sunny weekends, that's why I prefer to go there on weekdays. The outside part is very beautiful, full of flowers, with a small pool and nice tables. The restaurant serves mostly seafood, but if you feel as for coffee or gelato only, that's no problem, just sit in bar section.
There is an awesome view of the sea, which will let you relax after hours of sightseeing.
It's good to stop there after visiting Ostia Antica, there are only 2 train stops more to the direction of the sea.
