Breakfast is my favorite meal to eat out, especially late on a weekend day. We just don’t have many old-fashioned diners near us anymore - mostly just the chain places, like IHOP, SD.
We still have a few of the Tastee Diners in MD, in the old Comac diner-car buildings. I like the one in Laurel:

Go to the one in Bethesda. Good food.
