Rex Pizza At Rex Pizza, you get much more than just pizza. Check out our huge selection online for delivery or come in and taste our hoagies and oven grinders. And, of course, for a restaurant on Race St. in Philadelphia we would not be complete without our Philly Steaks. We have nine different versions and one, or all of them, are sure to please. Try our Beef Rex Royal with mushrooms, green pepper, pepperoni, sauce and mozzarella cheese or the Buffalo Chicken Steak with buffalo sauce and cheddar cheese. Of course, if it's pizza you want we have that plus strombolis and calzones as well. And all at prices to suit your wallet. Order Online Payment Options
