Excellent free scenic views of the city and the river. Free wifi in the cafe upstairs. Great place to see cultural performances.
Surreal backdrop for night shooters (challenging for the novice) and great perspective views on the Mall anytime of day.
Awesome outdoor bar with a beautiful view to the Georgetown Waterfront. A must for all visiting or living in DC. Make sure to get the ice bucket of Coronas in the Summer
Bring a sketchbook if you like to draw. Evening is best with the sunset shining and the reflection at its brightest.
