"I couldn't believe what I was hearing. I was in total shock," Braun told WJLA. "The anger has subsided and I'm left with sadness for my son and his future struggles of being in public."
Restaurant officials apologized to the family.
"We strive to make sure all guests feel comfortable and welcomed in our restaurants and we fell short," the restaurant told WJLA. "We're learning from what happened and training our team so we can better serve our diverse guest population."
The restaurant offered the family multiple gift certificates and a donation to an organization that works with Killian, WJLA reported.
