I've been here twice. July 2013 my companion and I both ordered the mahi mahi and loved it. The atmosphere was great and walking around the District afterwards is always fun .
We returned in February 2014 for dinner again, this time I ordered a steak and he ordered a seafood medley. The seafood was great. The steak - bad. I ordered it pink/medium and it came well done and dry. Later we both suffered gastro distress (full on food poisoning symptoms for me), presumably from the seafood, as that was the only dish we shared.
We'll probably be back, since its a favorite for out of town guests. But our dinner selections may stay on the safe side.
