There are restaurants that open so softly, it’s weeks before the cognoscente wander in.

And then there are spots like Rocca, which opens today. Well, let’s just say this one’s making a splash.

In fact, waves and watery hues literally, er, bathe the place. Partners Michela Larson, Gary Sullivan, and Karen Haskell pulled out every gosh darn stop, from the stunning U-shape bar to the second floor’s lovely, warm-hued dining room. From chairs flown in from Italy and mosaics resembling Cinque Terre graffiti to cork walls evoking the cliffs of Liguria.

And kick. ass. food.

The cuisine is inspired by Larson’s Ligurian ties, and seafood plays a big part. Go for the whole-roasted fish or buridda, a fish stew served with toasted ciabatta. Dive into plates of achingly fresh pasta like the corzetti layered with red-wine braised rabbit or capellini piled with tiny clams.

In fact, get it all. Nothing goes for more than $24.

Which means that, despite its watery theme, this place won’t leave you all wet.
