Chipotle isn't franchised. All locations are company owned, built, and managed.
But anyway:
Restaurants are pretty high risk, but being a franchise lowers that somewhat. You'll need a lot of capital ($75k-$100k) before a franchise will even consider helping you. Lack of experience will also hinder you. If you're really serious about it, look up how to do market analysis and business plan so you can form a portfolio to demonstrate the validity of opening a new franchise location.
