This is a "locals" place. Period.
I went there by myself on a business trip for dinner. It was recommended by the hotel staff.
Place is a local legend and has a historic background. Outside of that, it is akin to every other "local hangout". Nothing spectacular but again not hateful.
I ate at the old bar, along with the locals and listened to a waitress complaining that she had a "bump" on her breast. So other people working, decided to personally check it out, right at the bar.
The salad, while large was quite unappealing. It had been made or had set for quite some time before it was placed in front of me. Dark, slimy lettuce just turns me off completely.
The steak I ordered was tasty, cooked as requested and was alright. For the price, it was excellent.
I ordered a glass of wine and was quite surprised that it showed up in an individual bottle, not chilled and served with a side glass of ice. Nothing like watering down your wine.
Overall a pleasant experience, but not one I will repeat on my next monthly trip to Olean.
