I have such mixed experiences that I took the middle road. The service has ranged from disinterested and slow to very pleasant and slow. Sometimes - VERY VERY slow. I don't really get why there will be four employees having a social conversation at the same time tables need to be wiped down and clients are waiting for over 20 minutes for a burger and fries. This is consistent across DC locations (Dupont Circle, Gallery Place, 14th Street or Tysons Mall). Slow. If the food weren't so tasty - I would never return. But if the service were more timely and friendly - I would probably be tempted to visit more frequently.
