This Wonkette item brought back memories, though fewer than had we spent less time at the Tune Inn. (Interestingly, that second link makes it sound like a nice place.)
Although JJV probably already knew this, I learned from the Wonkette piece that the establishment has a basement. Having experienced the delights of the first floor I can only imagine what the basement is like.
The post title refers to the long-gone days when there was only one beer on tap, making it very easy to order. If you couldn't slur "glass" or "pitcher" you knew it was time to go home. Most of the time, anyway.
