I can tell you need some help with business planning, and an Ag site may or may not be the place to get good advice with a restaurant.

If you are serious, one of the members involved should spend time working at a restaurant, waiting tables, cooking, cleaning
and all of it.  Don't start one up without experience.

This is an expensive venture, and as mentioned above it is not easy and the success rate is not good.  So don't just put money
down a rat hole.  A business like this is like a dairy farm, work every day, morning, noon and night.  A sad thing I will mention is that
in Minnesota, there is a dairy farm calling it quits every day, according to the ag news.  I really feel for those families.

I will mention my experience from many years ago, when I was a small town banker.  We had a closed down restaurant loan customer, and
the smell of rancid stinking oil in a fryer, when things failed.
