We just moved here from the Big Island and were also thinking of opening a Shave Ice business! The so called "Hawaiian Ice" is actully "Snow Cones"! It's horrible how people use "Hawaiian" to describe something that is not Hawaiian at all! I would say if you go ahead with your business please make it true to what people who have eaten the real stuff expect and you should be very succesful and have many happy return customers! Don't be surprised to find many Hawaiian's driving many miles in search of the real stuff! Aloha will be nui loa!
Aloha! P.S. I hope we're not planning on opening the same business in the same town! LOL
