Just across the tracks from the Manassas train station and the Lloyd E. Harris pavillion, Foster's is perfectly placed for hungry commuters and visitors to Old Town Manassas alike. A long wooden bar runs down the side of the main room, and tables lines the windows on the other side. The house specialty is a chargrilled burger, with a dazzling array of toppings. It also serves extra-thick milkshakes in chocolate, vanilla, and strawberry.
