This is probably a silly question but if the priority is less about making money and more about enjoying the lifestyle . . . do you need to tie yourself to a single concept? Could you keep brain on his toes by telling him he can change the menu any time he gets bored. Because I am pretty sure that as soon as people have eaten your food once, they will come back for more of ANYTHING you choose to make. I know I would.

PS: don't listen to me because I don't know anything. Except that I enjoyed reading this very much.
