We showed up in this restaurant at 9:45 PM, although the restaurant was scheduled to close at 10 PM. The hostess/waitress led us to a booth. A couple of other tables of customers were still in the restaurant. We ordered our hamburgers, fries, onion rings, and root beer float. Our food was brought to our table at 9:58 PM. My husband was brought fries rather than onion rings, but we did not mention the mistake to the waitress because it was almost closing time. She was friendly and checked in with us off and on to make sure that we were happy with the food. The burgers seemed to a good quality, and we enjoyed the taste. The fries were fries.
4-28-2018 update: I ate at this restaurant again this week. My husband really likes their hamburgers. He thinks that the hamburgers are the best in Pittsburgh. Today I ordered macaroni salad, which was 5 stars, and a grilled cheese sandwich, which was 4 stars. The waitress did not bring out my macaroni or utensils, so I had to ask for them. She also fumbled with our payment at the end.
