Get here early as there is a line. The diner itself is small so you're pretty much standing over folks while they're eating, which is hilarious. The service is hit or miss, honestly. We had one lady who was very quick and nice and kept checking on us while there was another lady that just looks mad at the world like she hates your guts for even asking for a glass of water.
Food is diner food and hits the spot when you've been traveling from the DC Metro Area to a Steelers game and in need of nourishment.
