(ChicagoTribune) - Starbucks plans to open as many as seven stores that sell beer and wine in the Chicago area by the end of 2012. The Seattle-based coffee giant has been testing a more community-oriented store concept to boost traffic in the evening for more than two years. These stores offer savory, high-quality, small plate options like cured meats over the standard pastry case fare, and beer and wine in addition to the usual coffee and tea. Starbucks has also been experimenting with live entertainment, including music, poetry readings or theater, depending on the neighborhood.
