If you do not have knowledge or experience, I suggest you at least gain knowledge first before plunging headon to start a restaurant business. Restaurants are a hard business -- and COSTLY too. It is not something you can start with $5000 so you need to make sure you know what you are doing
It is always best to start your business by putting together all your questions and finding answers to them. You can do that with a business plan (and if you plan to look for investors or apply for a loan, you need to present your business plan). Here are some sample business plans that you can use
