I know that when I asked, most people told me to try trial and error, and just try to go to every place that you can find. Unfortunately, I can't travel often due to poor health, so I prefer to have at least a 50-60% likelihood that I will be able to create a positive social connection with someone.
If your health isn't impacted too much, maybe the trial and error suggestion would be helpful to you. It's good that you are willing to even try, so good luck.
Also, the people in my area laugh at non-drinkers and usually say to try going to a church event. Maybe that would work too.
