If this is your first business venture, I would strongly recommend that you talk to a business counselor before you do anything especially spend money. I’d call the local office of SCORE (go to http://www.score.org and input your zip code to find the chapter nearest you), the advice is FREE. Ask for someone who has a background in restaurants and they’ll try their best to match you with the right counselor.

The counselor at SCORE will most likely advise you to write a business plan which is very good advice because it will force you to dig out all of the start up details and the costs of starting a pizza restaurant and force you to also understand all of the aspects of this business including the customers you’ll concentrate on (your market ) and how you’ll get them to find out and want to come to your fabulous pizza restaurant.

The location of the restaurant is important but doesn’t make it successful. To prove that all you have to do is walk down a street in your town where there are several restaurants all in a row and you’ll find one or two that are empty while the others are very busy. It has to do with menu, ambiance, and your reputation at the beginning and over time.

You also have to have food handling licenses, the right zoning, the right city and county licenses and permits and you have to be skilled at negotiating with your landlord about who’ll stand the cost of the build-out or the changes to the premises to make it ready for your look and feel. You also have to worry about the normal business planning and management issues related to starting up any business.
