Too often is the term "instituition" used when describing an eatery. Too seldom is that term used to describe "The O". If you're looking to feed an army of hungry college students then this is absolutely the place to go. What can one get at "The O"? Well, try delightfully greasy pizza, thick hard hot dogs. triple thick milk shakes, and a mountain of french fries so large you almost need a wheelbarrow to carry them. God only knows how many weekend afternoon hangovers I drowned in a sea of french fry grease, ketchup, and cheese.
The place has the right amount of dirty to make a hungover college student feel at home.
To visit Pittsburgh more than twice and not go to The O is a tragedy. But some advice, go in the afternoon or early evening. Late nights are very busy and sometimes the place is frequented by some unsavory characters.
