April's window treatment at Bantam + Biddy uses colorful puzzle pieces interlocking in support of the Autism Speaks puzzle piece fundraising campaign. Midtown neighbors already know of the Ansley Mall eatery's devotion to assisting local charities, and Autism Speaks occupies a special niche in Co-owner/Executive Chef Shaun Doty's heart. If you're in the area to eat, shop, visit Piedmont Park or the Atlanta Botanical Garden this month, Doty and Co-owner Lance Gummere encourage you to stop in and purchase an Autism Speaks puzzle piece. You'll receive a brightly hued puzzle piece -- with a place to write a name and a message -- to add to the window's $1,000 puzzle-building goal. Nothing puzzling about where the money goes. All money raised goes to nonprofit Autism Speaks, the world's leading autism science and advocacy organization, for funding research into the causes, prevention, treatments and a cure for autism. Will you be a part of the process in finding the missing piece?
