To expand on the meals for WARF 2015, the lunches on both Saturday and Sunday will be in food court type settings.
Saturday lunch in Baltimore will be at Lexington Market. My restaurant listing for them is here. Unfortunately with most of them private stands, they don't have their own websites. But as you can see from the list they have just about anything there. You'll surely find the standard pizza or burger fare.
Sunday lunch will be at Tysons Corner Center (aka Tysons I). The list I put together for them is here. This is a large suburban shopping mall. It has a food court on one end and another area in the middle where there are storefront restaurants where one eats within the restaurant instead of a center court.
Dinner on Saturday, when the most participants will be in town, will be someplace within the Washington, DC area. The plans are to arrive in Washington on Amtrak Regional #147 at 3:30 PM or whenever it happens to show up, sit a bit in the Club Acela, and then depending on where we end up having dinner, leave and head for Metro with enough time to get to that location. Where will dinner be? That is still in active discussion. Anywhere within a reasonable walk from a Metro station that is reasonably priced and meets the attributes we've learned over the years (separate checks, easy access/egress seating) we need to follow is a possibility. Thus both downtown and suburban locations are being considered, with the latter more likely to be within everyone's budget.
A smaller number of people may be in town on Friday and Sunday evenings, and dinner those evenings can also be discussed among that smaller group once Saturday is settled.
