Make people happy by serving low cost meals in big servings. If your asking me if it is a quality food? Absolutely I worked in restaurants for ten years, I know the risk of food poisoning and of course I know food safety.
Its not easy starting small, but its a start sooner or later people will notice your product and little by little you will become known. And that's the time to go big.
Learn to be patient and learn to love the customers. Don't forget that price and serving size does not define your product, its quality and cleanliness.
