Everything that comes out of Mason's is a delight, and it's rare to visit without sampling something you never thought could be delicious as ice cream - think Froot Loops Cereal Milk or Whiskey Eggnog. This is not the place you go in and order simple chocolate or vanilla, though there's always a trade-standard-equivalent for those who refuse to challenge their tastes.
Even better? They make everything from scratch, right there, and sometimes on-demand: if you really adore a flavor and don't mind buying it in bulk, put in an order any time of year and over a few days they'll mix up a batch just for you to take home and enjoy. I haven't yet availed myself of this only for fear that I'll take it home, lock the door and feedbag the whole thing in one sitting.
I've been a devotee of Mason's since they were the friendly folks with the stand at the nascent Cleveland Flea; Jesse and Helen are what I would describe as a chill-power-couple. Having floated in their glow like some kind of dairy-treat-loving-moth for a year or so now, I can both claim a serious bias and attest that despite my fangirling, I haven't been burned yet.
