The young lady was so helpful and understanding as I am recently diagnosed Celiac. She directed me to a flyer of their allergy information by the drinks and ketchup counter. I got a burger and gluten free bun. Gluten free bun was delicious. Too much bun for me though so I took the top half home to enjoy with a sandwich at home :) The lady also recommended a lemon ice with fruit (I picked raspberry) it was so good! She said another woman who comes in frequently gets it and likes it. It was very refreshing. Sioux Center Culver’s is top notch service. Also, I made a drive through trip the other day and asked for no bun (I was going to be lazy and skip the allergy part) and the man asked if it was due to an allergy! I loved being asked instead of having to say it myself!
