As mentioned before, a business plan is a good place to start.
A lot of people get into the restaurant business because they are great cooks. My concern is that you might be lacking some of the other skills necessary to run a business. Think about all of the other skills you need.
-You need to be good at research to figure out the best location, market and product.
You need to be good with numbers not just to keep track, but to forecast.
You need to be good at organizing and logistics to make sure everything is in place where and when you need it.
-You need to be good at marketing to bring in the business
- You need to be good with people to manage your employees.
