Frozen mounds of kosher-certified yogurt spill from self-serve stations at Lemondrop Frozen Yogurt, awaiting more than 50 toppings. Armed with an empty cup or an umbrella turned upside down, guests capture the frozen rivulets of tahitian vanilla, espresso, cookies 'n' cream, and greek honey. They then sprinkle on fresh fruit and candy toppings such as blackberries, strawberries, chocolate-covered pretzels, and peanut-butter cups.
