Sounds like you have one heck of a plan there not to mention the experience needed to pull if off. That would be one great way to invest in yourself. Though just like any investment there is always a chance of it being a complete success or even a failure sometimes.
Though that is just how things go in any investment type. There are always risks and chances that you have to take.
I would imagine that if you found the perfect spot for your restaurant then you have one hell of a chance to really make a great investment.
I hope that if you do decide to make this investment in yourself that it turns out to be a complete success and that you invite me for a free dinner some day.
I am also glad that you found these videos here useful. Hopefully they will help you along in the start up of the restaurant of your dreams.
