On the outskirts of Old Town Manassas, Deli Depot has been a local secret since its opening in 1987.  Walking in, the first thing you notice is that behind the counter the short order kitchen is open to the room, and the cook is usually hopping.  There's a lunch rush from the local businesses around noon, but the line moves fast.  Deli Depot is the home of one of the best Reuben sandwiches in the Northern Virginia area, and it's justifiably proud of the onion rings.  If you're in the mood for a real deli-style experience in Virginia, look no further than Deli Depot.
