I don't know if it's still there, but the Manayunk Diner. I haven't been in that area since we moved out of East Falls in 2015. The diner was good, then closed for a while, opened back up under new management.

The "menu" was a printed piece of 8.5x11 paper, folded in half. The omelet that I ordered came out gray. We were the only people there, and the staff acted like we were wasting their time coming in to eat there.
