What to do on a hot afternoon in DC? Traipse over to the DC waterfront. This is an upbeat place to hangout and have a cocktail or two! We biked over there the first day we spent in DC and had a few cocktails at Sequoia. We enjoyed the frozen mango margarita and the watermelon splash. Both were delicious and tasted like a second round! Sequoia has a large outdoor bar and patio with plenty of seating. If you’re traipsing through DC, you must stop at Sequoia.
