Since its heyday in the '70s, frozen yogurt has lost its tang, with most contemporary varieties barely distinguishable from ice cream. But Red Mango holds itself to a higher standard. The Korean-based company makes sure its product contains live active cultures (S. thermophilus, L. bulgaricus, L. lactis and L. acidophilus), though it is not legally required to do so. The result is sweet and creamy, yet identifiably yogurt-y.

Red Mango was founded in Korea in 2002 and now operates dozens of locations in the United States. Along with the Plainview store, there are also locations in Deer Park, Massapequa Park, Greenvale and Oceanside on Long Island.

The menu is tightly focused. Aside from the "original" (i.e. plain) flavor, there is green tea and one seasonal flavor. All the flavors are nonfat and contain about 100 calories for 1/2 cup. (That 1/2 cup, a small serving, will run you $2.50; a medium is $3.50; a large, $5.50.)

Toppings, for the most part, are of very high quality: really ripe berries, pineapple, kiwi and mango, pomegranate seeds, almonds, miniature real chocolate chips (Ghirardelli, no less), dried cranberries, coconut and mochi, the glutinous-rice-confection somewhere between Turkish delight and salt-water taffy. Then, there are the toppings seemingly designed to counteract the yogurt's nutritional purity, among them, Cocoa Pebbles, Fruity Pebbles and Cap'n Crunch. Apparently, it's all about choices.
