Lonie Walker's not your average Chicago club owner -- which is good, because her club, the Underground Wonder Bar, is far from your average Chicago club. Since 1989, the wild child has made her Gold Coast spot a haven for local musicians of all stripes (including the rockin' Walker herself), pioneering green business practices and remaining a committed charitable donor along the way.

Sadly, making it to year 21 might prove difficult, as the club's building, at 10 East Walton, was recently bought out. If things don't work out, a lot of people will have the blues, but Walker and her pals aren't wallowing. Instead, they're partying, celebrating a different year in the club's tenure every day, starting with a tribute to 1989 (complete with de-inflated drink specials) tomorrow night. The fun continues over the next few weeks, with the big 20th anniversary bash on November 15, featuring live music from 4 p.m.-4 a.m., drink specials, food and prizes, with proceeds benefiting the People's Music School.

So whether you've been a faithful patron since the days when the Gold Coast was one of the seedier sections of town, or you've yet to make a visit, now is the time to stop in for a trip down memory lane. Lonie will be waiting.
