Obama liked Pi Pizzeria so much that he invited the owners to cook at the White House, and while you might not have a mansion to show your affection, Pi is still worth checking out. There are a few outposts around St. Louis, but the Delmar Loop location is the only one with outdoor seating and it’s a good place to start a night out on Delmar. You can choose between the cornmeal crusted deep dish and the thin crust, or just try one of each if you come with friends. The Delmar, which includes barbecue sauce from Pappy’s, and the meatball-topped Kirkwood are both great options, but you can’t go wrong.
