Well I really enjoyed Cafe Orleans in the DL park, I thought that was really wonderful.
But in DCA its a bit different as there really arnt any sit down service restaraunts to eat at besides the Wine Country Trattoria, the Vineyard room, and Ariels Grotto. But if im in DCA I like going to the Award Weiners and getting a hot dog through counter service and sitting at the tables beside the Disney animation studio, or going to the Pacific Wharf cafe for some soup or a sandwhich
