A group of mostly African-American people celebrating a birthday party at a Buffalo Wild Wings in suburban Chicago allege they were asked to change tables…because of their skin color. Justin Vahl says he was at a Naperville restaurant last month with children and adults when a host asked him about his ethnicity. Vahl is multi-racial. Later, a manager asked the group to move because a regular customer didn’t want to sit near black people. After several managers tried to move the group, they left for another restaurant.
