We were never offered GF buns in May 2015. We ate hot dogs and hamburgers without them. It was the Panama Canal Cruise, so they may have had different foods. The "Hamburger bun" in the MDR was the same dinner rolls they served. Hard and tough...not like the ones at Disney Parks made by Gluten Not Included Bakery. I ended up getting a "lettuce wrap" which, really ended up being a piece of lettuce, a patty and topping on my plate the next time I ordered a MDR burger. So it was more like a salad. No wrapping it up. The lettuce at Pluto's Dog House was shredded, so no lettuce wrapping there either (I specifically asked for whole lettuce pieces). The hot dogs were always given to us without a bun. But the fries were good
