I grew up in a family that was in the restaurant business. I would advise against it.
As others have said, either you, or someone you trust completely with a lot of skin in the game, must be present at all times. All of your employees will steal from you. Even trusted managers. And if there are multiple owners, invariably there are going to be multiple ideas on vision, process, etc. Almost literally, too many cooks in the kitchen. It's tough business.
My friends finally stopped bothering telling me I should open a BBQ restaurant when I told them all the stories about the one that we used to own.
