I was looking at the articles on Entrepreneur and came across an article on one-hit wonder businesses. It is about businesses that are making money by focusing on only one thing.
There is a restaurant that only serves mac & cheese. It serves it many ways - but that is all it serves. And it's making money.
There is a restaurant that only serves grilled cheese sandwiches.
Craziness. I think I have read before too about a place that only sells PB&J sandwiches.
Such a simple idea,but so profitable. I need one of those!
