Can you do the work of a Culinary?

There a lot of creative ways to imitate a career. If you have get to work you could create a storefront. Cook your food and set it for sell. Then you could either play get to work as the store owner and sell the food. Or you could play another household and go to the store and buy prepared meals. I find this a much more realistic way to play since not all sims will be at cooking level 10 but many have the money to purchase good meals for their families. 

If you own a restaurant you will not be cooking. You will be managing employees and schmoozing customers. - FYI.
