Good golly, Miss Molly - do you ever need a business plan!
And the foregoing posts are not one, they're pipe dreams, and no bankers will even talk to you about the kind of loan it would take to implement your idea. Especially these days.
If you want to be a restauranteur in Hawaii, go there (cheaply as possible) and get a job in a restaurant that seems closest to your dream restaurant. Probably as a dishwasher given what you say about your culinary experience.
After a few years, you may know enought about it to get a start on your own.
Good luck, but you'll have better luck if you fool around in some restaurant (not yours,) in Texas.
Don't get too close to the shore - it's going to be covered in oil.
