Man, Jack's is so awesome. It's cash only and it is CHEAP. This is a true glimpse into an OG yinzer bar and it is GLORIOUS. They are open almost all hours of the day - catering to the steelworkers back in the day who would want a drink after wrapping up third shift.
Do not expect anything fancy, but do expect that the bartenders are awesome. Every drink order will be taken with a "sweetie" or "honey" or "babe" and the drink will arrive strong AF. Also, for having a minimal "kitchen" .. the cheap food is surprisingly good. Get the fresh cut fries and cheese - straight outta the potato patch. Since the drinks are so cheap I tend to throw a few back, and the cheap food options are there to bring me back!
I really love this local spot. If you're in from out of town, it's a must to check out.
