I'm kind of upset that it took me this long to discover Ritters Diner. My parents had told me about it, but as I'm getting ready to leave Pittsburgh, I finally dined here. Perhaps the best thing about it is the hours. It's hard to find restaurants in Pittsburgh that are open until the wee hours of the morning. I ordered a bacon cheesburger with fries which were delicious. The restaurant is rather old-fashioned with the booths, but very clean. My friend ordered mozzarella sticks. It was the perfect meal and very quick. Just make sure that you have cash on you.
