We hit this after seeing Love, like so many that entered. I understand there's a cover later, but after the first show, there wasn't one, so we wandered on in.
Drinks are pricey ($8 per beer, more for mixed drinks), but tasty, and the environment alone is worth the visit.
All that, and the music was great. :) Do visit it early if you want to avoid the cover. If you want it more lively, either come back and pay or just stick around.
