Weather should be pretty good by then - fingers crossed - wonder where we could do something outdoors... Cantina Marina perhaps?

Its early enough that we might be able to get reservations for a group outside on the patio - nice views of Haines Point, planes taking off/landing at DCA.

I have not been there personally - so have no idea what the food/service might be like. But was just thinking of something outdoors.
