A cozy informal neighborhood trattoria with an open kitchen in the back which offers excellent seafood dishes and pasta and good inexpensive wines.  And if ice cream is your favorite dessert, as an added bonus, the restaurant a three minute walk from Grom, the super delicious gelato shop.  If you order the whole grilled fish, the waiter will fillet it at the table. Cash only.  Favorites:  spaghetti with clams; sepia with scallops; whole grilled bronzino.
