5 years ago I was commissioned to make studies of International Franchises coming to RD.
First ofall you must think like a Dominican, eat like a Dominican and spend your money like a Dominican ; then you will refrain from trying to make a buck by changing the diet here,
The most successful fast Food restaurants here are pizza. But one does not need an International Franchise to make and sell Pizza.
Your investment is your business , and I wish you well.... just be careful of your motive.
Return on investment may not be what you would expect.
And I am a positive thinker, with a thousand good ideas which remain in my computer.
Good luck.
