Lap and Library were where Buffalo Wild Wings is/was. They were separate, and then they operated more or less as a single bar sometime in the early 90's. The Lap was a beer joint and the Library had music acts most nights of the week. Friday nights before football games were crazy. They usually had a big band play - Sage, Mel and the Party hats, Jason and the Scorchers, Unitz, Velcro Pygmies, White Animals (?).
Ivy's was a pickup joint where Rumorz is now. Before that, it was on Lake Ave. roughly where Cool Beans is. I think it was one spot east of Cool Beans' location.
The Longbranch Saloon used to be where Regions bank (whatever's next to Hannah's - same side of street) is. It was a complete dump and therefore awesome.
There used to be a lot more activity back on Lake Ave. There were three frat houses in that corner of Lake/18th that is now a "park" and a parking garage. There were several versions of a bar that sat where the Renaissance condos (the smaller ones) now sit. The huge condo building at Lake/18th was a bunch of apartments.
Ruby Tuesday was where the Gnome is now.
Hawkeye's was at the corner of White/17th. There is still some sort of bar/restaurant there. They had bands several nights a week in the upstairs.
Quarters was where the Goodwill store is now - couple spaces away from the Yacht Club bar now. Another beer bar.
Roman room was where McAlister's is now. Great subs/etc. and beer.
