From their fantastic food to ambience that their restaurant provides (specifically their outdoor seating) Hank's is a must try. They have another location in Old Town Alexandria that I have yet to visit which may be more convenient to any readers from Virginia. To residents of the District they have prime real-estate and their outdoor seating provide a tranquil experience when the weather is nice outside.
Prices are a bit expensive which I why I can not go more often but the freshness and flavor more than justify it. It can get busy especially when the warm weather makes sitting outside alluring. So if you are ever in the mood for fresh seafood give Hank's a shot you will not be disappointed.
