I've quasi-explored this and there are a few obstacles and barriers to entry when specifically trying to establish a progressive dinery.
-
The best way to not be a mini-tyrant is to perform most day to day operations yourself. However...
-
Americans want variety like no other. 31 flavors? Make it 32. 35 would be better. More dining options will require more labor and source materials, and create a huge potential for waste.
-
Most restaurants exist on thin margins of profit and usually flourish solely based on capacity. However, there are some styles of food that buck this trend (Italian and bbq are good examples because the source products are cheap; it's all about the prep).
-
Retail storefronts are a ripoff. You will always be swimming upstream paying rent.
Conclusion: in order to sustain and not be a tyrannical jerk my only suggestion is to open a roadside hot dog, bbq, or pizza stand and have 0 employees.
