Sometimes at four in the morning you need a place to eat, and, for that purpose, Ritters does its job. Otherwise the food is pretty mediocre. Remember if you can after a long night out that this establishment is cash only.
You are never going to get great service here, and for the most part at night when the entire place is packed full of belligerent drunks why should you? The waitstaff does their job: takes orders, brings out the food, and refills your drinks, but don't expect much more and surely don't expect to have all your requests pampered. I feel bad for the waitstaff who have to deal with drunks all night, especially on the weekend.
This is a Pittsburgh landmark, nice diner vibe, and a place where I will always have great memories. Though the food is pretty mediocre and slightly overpriced for the quality I will always keep coming back here out of nostalgia.
