A favor: Thursday night, make plans to meet friends for a drink. Please.

Throw caution to the wind and mix wine with beer. Have beer before liquor. Close down the joint.

Or if drinking isn’t your thing, order a soda. A dozen of them. Drum up a tab that would make JayZ proud. (But please take a cab home.)

Because a whole slew of fine establishments will be donating a portion of their sales Thursday night to AIDSCare, a Chicago-based organization that supports people living with advanced HIV/AIDS.

So be sure you go to one of these spots: Atwood Cafe, Big Chicks, Bravo Lounge, Bucks Saloon, Buzz, Celebrity, Cell Block, Chesterfield Club, City Saloon, Closet, Cocktail, Encore Liquid Lounge, Flight Wine Bar, Gentry, Hangge-Uppe, Innjoy, Jackhammer, Kit Kat Lounge, The Lakeview Broadcasting Company, M Lounge, Metro, Moonshine, Nick’s Beer Garden, Nick’s Uptown — hang in there, almost done — The Note, Original Mother’s, Phyllis’ Musical Inn, Red Line Tap, River Shannon, Smart Bar, Southwater Kitchen, Spin, Spoon, Streeters, Suite Lounge, Tavern 33, Tequila Roadhouse, Timothy O’Tooles Pub, Touche, T’s, Tsuki Lounge, Victor Hotel, Village Tap, Vintage, Wet, or Zocalo.

That’s right. Playing your part is as easy as walking out your door, down the street, and finding a place to grab a drink.

Gives a whole new meaning to drinking responsibly.
