I voted beer...but scooped, from a GOOD shop. Around here, we have Honey Hut, and another place I can't remember right now. In Vermont, the fuckers have Ben and Jerry's stores.
I prefer pistachio, butter pecan, and Chocolate almond.
I've never had a really good milkshake, which I find disconcerting. I've had plenty of scooped in my day, but I really prefer soft serve, it's just too bad that there are none in my area.
