|Cotton candy at the Columbia Mall|
Look near the water feature in the center of the lower level -- near where they sometimes display automobiles. We found a cart selling cotton candy right from the machine. Fruit flavors, along with pistachio. Mrs. HowChow had bought some earlier in the summer, and our second $3 bag was just as airy and sweet. They're running a cotton candy machine at the stand, so it's fresh.
It's a quick treat. But it's good enough that I'm trying to figure a way to serve it to friends this weekend.
(Update Sept. 2013: They moved the cart a little closer to the food court after installing a cupcake bakery under the escalator near the water feature. You can still buy great cotton candy.)
