I'm not generally a fan of shaved ice, but I like Snowflake because they aim for a creamier, softer ice compared to most shaved ice I've tried. I love that Snowflake offers so many flavors and toppings; although the set combinations are very good (the black sesame is a personal favorite), I strongly recommend trying different flavors (even plain!) and topping combinations because so much of the stuff is so tasty here.
Negatives are that the shop is small and has very little space for seating, and sometimes there aren't many employees working, so it can be very slow. Consider getting your order to go (they have lids for the cups) so long as they won't melt in your car!
