OMG it's so buttery! I know I should be watching my sugar intake since my next fight is coming up, but I was really craving :'( The Sans Rival McFlurry did the trick. It was so rich I wasn't able to finish the cup. I also tried their Black Forest Coke McFloat, but I think it had too much ice in it. Just took two sips to finish the drink, and all the rest was ice.
