Luck is certainly an element in everything, but we need to be careful to not let the existence of luck blind us to all of the elements that actually are under our control.

For example: you can't, really, have two equal bars. They are going to be in two different locations, and one of those locations is likely better (even if only slightly) than the other. This can be enough of a difference to create a critical mass of people to get the "Cool, this bar is always hopping" effect.

"Zero distinguishing differences" usually just means you haven't analyzed deeply enough.
