When in Waikiki, Island Vintage Shave Ice is your best bet when it comes to this Hawaiian frozen treat. Their little shack is located right outside the Royal Hawaiian Center by the escalators. It's hard to miss the long line leading here. They have set...menus to choose from as well as an option to create your own like most other places. I like the freedom of choosing my flavors and whatever they may be, I always add ice cream and condensed milk. Only here do I add mochi because their version is insanely amazing. It looks like a powdered cloud that's pillow-y soft in texture. Just wow. Flavor wise, count on me to pick anything tropical and here I've had lilikoi and pineapple together as well as lilikoi and yuzu. Yuzu is hands down a must-pick flavor.More
