Look out, Dairy Queen. ‚ Lots of restaurants are now making their own soft serve; I just had an olive oil version last week at The Purple Pig, and since it opened, Belly Shack has had a beguiling vanilla (with a hint of coconut) topped by caramel sauce and an aromatic shaving of Saigon cinnamon. This stuff is so good, I don't need to wait until warm weather to dig in. The chocolate-bacon is a close second, but after you try the caramel cinnamon, you'll never look at soft serve quite the same way again.
