Chef Shawn Gallo said the singer also posed with him when he asked for a picture, reported E! online.
"I called my mom to tell her Swift was there, and she wanted me to take a picture because she is a big fan. My son has autism, and while I'm at work my mom and my son love to listen to her music. He loves her music!," he said.
"It was so kind-hearted of her. My son Shawnee is 11. It was my son and I's first concert we've ever been to! It was really special," the chef added.
