We were at the Smithsonian and came across this huge McDonalds attached to the Smithsonian Museum; it is its own attraction. It has 22 lines. We were here early so we did not get to see the craziness of this McDonalds but I would assume during prime time, it would be super crazy and 22 lines would not even be enough. We ordered our breakfast and were quicker serve within minutes. We ate in the upstairs seating area and off we go to explore more of Washington D.C If you ever go here, it will be nice to just this unbelievable McDonald’s.
