I ordered a double deluxe basket (burger + side+ drink). I asked about the fryer, and they do not have a separate fryer for french fries, so I ordered a side of mashed potatoes (I asked to leave off the gravy and put butter in the side). The order came out in two separate bags (good because my BF doesn't eat GF at Culver's normally), but mashed potatoes with gravy came out with both orders, and I know their gravy is not safe. So I gave him my mashed potatoes.
The bun was steamed and came with the burger patties in a box with the toppings, which is standard. However, I still got glutened, and had forgotten it was what happened the last time I ate there. If you're looking for a Culver's experience, go to the Superior one. It's where I feel safest eating in Superior, and I've not been glutened there (and the french fries are in a dedicated fryer)!
