It's not called Zingers anymore, but this app is calling it that. I've been going there since it was called Creekside, before Zingers. I've loved them all! It is really convenient to have this good restaurant right in the neighborhood! They have great gluten free options, the gf buns are excellent. The manager said that more food choices will be on the menu in the future.
