Basically The Same As Any Other Bar's Happy Hours... Usually Wing Specials...
From what I remember, they have daily drink specials and happy hour is half off domestic and well drink. I'd probably call if there's something specific you drink just to see if it's part of the special. Here's the link to their page with specials: https://patrickspub.org/daily-specials/
