I went to Zen Frozen Yogurt & Coffee one evening because a friend of mine discovered that they have the Disneyland like Dole Whip drink.
The shop is like Menchies or Qoola with self served frozen yogurt dispensers, the dole whip drink isn’t on the menu so you would need to ask for it.
The dole whip was pineapple juice topped with dole whip frozen yogurt. The juice part was pretty sweet, but the frozen yogurt had a bit of sourness so together they were delicious. Compared to the original dole whip at Disneyland, it was pretty close; just missing an umbrella.
