www.austinchronicle.com and
www.austin360.com are good places to find shows if you want to do live music. Take a stroll around Town Lake and end up at the Congress St. bridge near sundown to see the bats. There are a ton of great restaurants downtown or near downtown - Roy's, Fleming's, Eddie V's, Roaring Fork, Uchi, Gumbo's, Matt's El Rancho, Chuy's (the one on Barton Springs), Shady Grove, and Polvo's are some of my favs in that area. The Broken Spoke is a trip. If you have a group and/or just want to take a drive out into the country, The Salt Lick, Gruene Hall, or Coupland Dance Hall can be fun but will probably be pretty dead at that time. The Bob Bullock Texas History Museum is also pretty cool.
