I would recommend only using the bar as a networking venue. If that's the reason you can't find another bar to frequent, I'd stop using it to date altogether. I mean, if it's supposed to be for business networking, make it for that, and, that only. Just ignore the guitar player. Who cares if they're starting at you? That's childish. Do your own thing. Seriously, though, I think the biggest mistake you're making is mixing business and pleasure. Find another bar to take your dates to or to pick up guys. Stick with this one for networking. Or maybe I'm misunderstanding what you mean by networking?
