Tucked into an old industrial area, House of Philly specializes in take-out and delivery. Although there is a small eat-in area with a few tables, the size of the open kitchen and the constant coming and going of delivery employees makes it clear that most of the business is geared towards that. The subs are some of the best in Manassas, and the huge selection of wing sauces makes this a great place to order from on game night.
