I want to start a restaurant and I need some advice or opinions?

My idea of this restaurant that I have in mind, is one that specializes on one particular food ingredient, (i wont say what it is) and I will incorporate it into many styles of dishes, including dessert. I want to ask everyone to let me know what types of foods you like or what ingredient you could see yourself using yourself if you were to have a specialty restaurant.

Chili peppers. However I certainly can’t see using this in a dessert. It’s a funny thing but Chili’s restaurant doesn’t use chili peppers in any dish unless they just don’t specify it. Why not go for the gusto and use it in almost every dish. Most people like spicy food anyway and it is a completely different kind of hot than jalepeno.
