What is the best way to "go out" by yourself?

First off, I just want to say that I KNOW that going out is better with friends

Second, some context: I live in a new city, and I don't have a super close friend group that I want to go out with every single week, so I'd like to have some options to just go out by myself if/when I have time without feeling like a complete loser in the process. I'll often go shopping by myself during the day or go out to just grab food by myself, but I'm 21 and haven't really done a lot of drinking so I'm not sure if "going out" for drinks by yourself or even just going to a bar to get food is a good idea for someone my age or not.

So anyone know what the best way to go out by yourself is while still getting some social interaction?
