This is such a niche demographic that I have to wonder how it was ever viable. From the article, it sounds like it was specifically targeted towards lesbians (not the broader LGBTQ, or LGBTQ-friendly), who are immunocompromised, and want to spend time at a bar socializing with other immunocompromised lesbians. That's going to be a vanishly small percentage of any community. I'm betting that total population in the city is what they would need to have at the bar every weekend.

As a business model, it would probably even be a stretch to target that one day per week.
