Bars or other businesses with a lot of younger, part time employees?

I’m 23M and recently single. Trying to get out there again. Never been much of a social gathering kind of guy, most of my friends have come from the part time jobs I’ve held down over the years. Now that I work full time with mostly 40 year olds, I’m looking for a side gig where can work with people closer to my age. Right now, I’m thinking about getting a job at a bar or restaurant in BG, would love any recommendations for somewhere closer. Looking for something I can do on Friday and Saturday nights.
