Strictly speaking, the Potomac River is not Il Mare, but as the watery view for one of the trendiest and certainly one of the finest seafood restaurants in D.C., the river certainly will do. Fiola Mare’s stiffest competition comes from its own siblings, Fiola in the Penn Quarter and Del Mar at the Wharf in the Southwest Waterfront. Sit at one of the many outdoor balcony tables and you’ll be gazing out at Roosevelt Island, Key Bridge, and a slice of Georgetown’s waterfront to your right, and the Watergate apartments and the Kennedy Center to your left. Great views are also available within. The sprawling modern interior has a front bar and a back bar, and more than one dining area in between. The quietly proficient staff serve up a slate of specialty cocktails, like the standout gin and tonic. Fabio Trabocchi shines in his mastery of Italian seafood (for Spanish takes on seafood, head to Del Mar). The menu’s different every day, but may begin with a taste of Italian caviar, followed by lobster crudo, and a too-generous portion of sea scallops with summer squash and a sun-gold tomato sauce. Also done to perfection are the pastas, like the blue crab rotolo. End with the bombolini: half a dozen ricotta doughnuts dusted with sugar, or the s’mores inspired campfire sundae with a caramel popcorn crunch.
