It is unfortunate that answers are never as clear as we would like. Numbers depend on many variables, carry out, delivery, gourmet, do you have a bar and geographic location. Food cost of 25 - 35% depending on volume and competition. Labor for hourly team members can run anywhere from 16 - 21% and management should run around 5%. A manager salary of $600 - $750 a week must also have a reasonable bonus system. Tie it into controlables and have a sales expectation bonus. You would probably want some experience in the industry, if you partner with some one or hire an experienced manager you will be highly dependent on them.
The pizza side of the food service industry is the only area I would go back into. I left ownership a few years ago for consulting. I do strongly suggest some research in the industry, it’s not for everyone. It can be one of the most fun jobs you can do. Go to work for another, even part time as a driver, just to see if it’s for you. It won’t take long to know if you are as crazy as the rest of us.
