Respectfully disagree. I don't think it's the bar. Seen a bunch of other bands there (The Lizards, Eggy, Bare Fuzz) and the music sounded great. I just looked up who plays what and see that Charlie Morgan is the lead guitarist. I preferred the songs Eric played and sang. Ymmv. One guy soloing the whole time doesn't do it for me within the context of the Grateful Dead.
Also what does the bathroom location have to do with the music?
