El Centro DF on 14th and T NW has a really good small-plates brunch, $39/person for unlimited tapas-sized plates and brunch drinks (bloody mary, agua fresca which is like a boozy punch, beer). reservations recommended since it's a smaller place and people tend to camp out soakin up those unlimited drinks. I believe Masa 14, which is next door, has a similar deal. El Centro DF is mexican and traditional brunch items; Masa 14 is asian fusion. Easy walk to U Street- Cardozo metro which is the green line, just like the ballpark.
