Blues Infused BBQ. When Windowsills Cafe & Marketplace (now WOODSMOKE BBQ & Windowsills Pies) participated in the 2014 STL Bluesweek Festival, the goal was to give festival-goers an experience in blues-infused BBQ that stood out from the competition. Stable Eleven created proprietary event designs, POP and product labels that garnered customer attention, appeal and a competitive edge.
