Best GF hamburger bun I’ve ever had, and I didn’t get sick! After a week of subsistence on protein bars and hard-boiled eggs, I was more than ready for a solid meal. The beef burgers are definitely the basic frozen food-service patties- nothing special- but it was fast, filling, tasty, and safe. And $12 for a GF double cheeseburger is a steal. I told the cashier that I had a gluten allergy, and that I understood that they had GF buns. I kind of had to walk her through the protocols. She did not mark allergy on my ticket, but when I asked, she confirmed that meat and buns are cooked on totally separate places on the grill. I asked the guy putting together my order if they could change gloves for a gluten allergy, and he said, “Yes, the protocol is that we change gloves and put down foil.” The spinach salad was a nice option too- some walnuts, craisins, and red onion. The dressing choices were a weird fit though- ranch, Italian, Caesar, Thousand Island. I picked Thousand Island and the dressing packet did say GLUTEN FREE on the back.

If you’re coming here for the Gluten Free bun option like we did for my celiac wife I would steer clear. The cashier didn’t know what the Gluten Free bun even was. She talked to a team lead who informed her all they have are hotdog buns and they’re frozen. I asked the manager to microwave a bun for us so my wife could eat breakfast. The manager did agree which was redeeming, however they didn’t have bagels or fruit. And the food that was given to us was cold. Would not recommend, especially for GF.
