We are two families visiting DC for a weekend. Big foodies BUT have four kids on tow ranging in age from age 2-6. Staying near zoo and also planning to visit National Building Museum. We love all food, except for very hot and spicy such as Indian. Foods utilizing local ingredients are favorites. Also love truly local and unique joints--doesn't need to be upscale. The neighborhood gems are always great. But most important is kid friendly!! And recommendations near the zoo or museum?
