Bantam + Biddy Lenox Square is looking ahead toward next month’s Walk Now for Autism Speaks Georgia 1.5-mile walk at Atlantic Station because it’s never too early to fly the banner to raise awareness and funds for a good cause. Nonprofit Autism Speaks roosts close to co-owner and chef Shaun Doty’s heart thus he’s designating Thursday evening, March 26 as a “Give Back Night” at Bantam + Biddy Lenox Square. Ten percent of all proceeds after 5 p.m. will go to Autism Speaks. Autism is the fastest-growing serious developmental disorder in the U.S., and currently, one in 68 children is diagnosed as having autism spectrum disorder (ASD). Buying an Autism Speaks puzzle piece for one dollar atChick-a-Biddy or any of the four Bantam + Biddy restaurants -- Ansley, Crescent Avenue, Lenox Square or Avalon -- is another way to help researchers unlock the Autism puzzle. The money goes directly to Autism Speaks, and your puzzle piece decorates the restaurant.
