Then you need to read this: The Thrill of Losing Money by Investing in a Manhattan Restaurant | The New Yorker
It is a wonderful read of a terrible experience.
Besides that, though, it is an entertaining but damning analysis of the restaurant business in cities like New York. (I imagine it is the same for most cities.) I think at some point there will be fewer and fewer fine dining experiences in cities, and the best food will come from places that are small and have very low overhead. And all those large spaces that were once filled with large restaurants will close.
If you still want to own a restaurant after all that, don’t say you weren’t warned! 🙂
