Meals on demand according to your own recipes
What about a business that would cook a meal of your choosing for you to pick up based on a recipe that you sent them earlier in the week, the day before, or that day.
Would have to be a bit cheaper than going to a real restaurant, but should be doable as there would not need to be alot of overhead.
Just a large kitchen with some good cooks.
Again you could pre-order meals in advance for pick-up.
Much healthier than fast food, you could really start using the cook books that you get every year and only cook one this out of it... ever.
