No OP, but restaurants are the most competitive industry possible. Anyone can start a restaurant, and lots of people want and can do it. Because it's intrinsically a physical business, the market reach is limited to a small area unless it's in downtown or a highly trafficked area - where it also costs a lot more in rent.

There's almost no way to make a restaurant profitable as many restaurants are a labour of love, basically.

As an interesting historical legend, Sequoia Capital invested in Il Fornaio, an Italian restaurant chain. It's not a grand concern but it has endured as an okay restaurant. Darden, OTHO, is a sizeable corporation that's growth oriented and has acquired some good regional chains. McDonald's, etc. are really real estate companies.
