Is it okay if I don't speak Korean well at a solo drinking bar in Seoul?

Hello! I am a foreign student living in Seoul. Recently, I've become interested in solo drinking bars where I can drink alone. There are a few near where I live, and I want to visit them, but I'm worried because I'm not fluent in Korean. I live in Gangnam, and I would like to meet new people at solo drinking bars that are closer, rather than in areas where English is commonly spoken. I'm trying my best to use Korean, but I'm concerned that people might not speak English well. Has anyone been to a solo drinking bar in Gangnam? Is it okay if my Korean is not very good, or would it be better to just stay at home? I would appreciate any advice!
