You've got a couple issues here -- starting a restaurant & starting a franchise. Let's tackle one at a time.
Re: Starting a Restaurant
The best routes to take are to research the process of starting a business as well as the industry you're interested in.
I recommend checking out the SBA, Entrepreneur, The Start Up Journal & Nolo. All 4 are great informational resources for the new/small business owner. I posted links for you in the source box.
Associations may be a good avenue to explore as well. These organizations will address many of the thoughts, questions and concerns you'll inevitably have as well as many you haven't anticipated yet. See the source box for some relevant links.
Research, research, research – this cannot be stressed enough. Read as much as you can about the industry. Here are some book titles that are relevant:
* The Restaurant Business Start-up Guide by Paul Daniels
* Restaurants That Work: Case Studies of the Best in the Industry by Martin E. Dorf
* Restaurant Financial Basics by Raymond S. Schmidgall
* Opening a Restaurant or Other Food Business Starter Kit: How to Prepare a Restaurant Business Plan and Feasibility Study by Sharon Fullen
* Upstart Guide Owning & Managing a Restaurant by Roy S. Alonzo
* The Restaurant Managers Handbook: How to Set Up, Operate, and Manage a Financially Successful Food Service Operation by Douglas Robert Brown
There are plenty of free informational resources out there. Check the source box for links to articles.
Re: Starting a Franchise
Again, associations are a good starting point. See the source box for some relevant links.
Here are some book titles that are relevant:
* The Franchise Kit/a Nuts-And-Bolts Guide to Owning and Running a Franchise Business by Kirk Shivell, Kent Banning
