Oh, what wonderful memories you've brought forward. My husband and I lived in Silver Spring for 30 years before moving to Kentucky in 1994. And, you're right, Ledo's rocks. Great pizza. We went back to visit one of your sons a few years ago and had the great fortune to have supper one night at Ledo's. Yum!
Of the top of my head I can't think of any DC restaurants that serve good old home cooking-type foods. Although, the Silver Diner did a good job of serving good diner food.
