Four months ago I remodeled a former Taco Place and opened an upscale Burger Restaurant (
Home Page) and as a former Pizza Parlor owner, I thought that I knew enough about the restaurant business that this would be somewhat easy.
The Pizza experience helped but I can see now that I should have got any job in any burger place for a while. It would have cut down on the experimentation and testing and wasting money on things I really didn't need.
If you have lots of experience in the Wraps business...great. If you don't...work in that business even part time to get a better feel for it.
Only other advice I can give is... it will cost more and take longer than you think.
