Definitely the McFlurry. Tried the swamp sludge McFlurry – sucker for the advertisements. Thankfully the green was really some sort of green smartie rather than mint with the brown being chocolate chips. Not bad. Just a bit more expensive than the mix/n/match Frosty which was half-the size and not very good . Caveat the frosty was half-melted by the time the server processed our order which is never good for an ice cream treat but so be it.
Anyways who cares? – The Blizzard rules!
