Personally I love happy cup beverages. My favorite flavors that I have tried so far are the iced strawberry and the kiwi flavor too.
I have tried the black ball jellies and the usual fruit jelly cubes too, and I like both but I much prefer the cube fruit jellies in my drinks.
The assortment of flavors to choose from here is impressive and the beverage is made fresh in front of you too.

came here thinking it would be somewhat on par with easy way. was sadly mistaken and ordered two artificial and strange tasting drinks.
