Rochester exists for the Mayo Clinic. There is little else to do or see in the city and no reason to visit Rochester unless one is gong to the Mayo Clinic.
Starbucks closed at 4 PM Monday - Friday. There is almost nothing else in the city except for the Mayo Clinic and other hospitals that have become affiliated with the Mayo Clinic. The city is safe with little crime but not much in the way of restaurants. I was given 3 recommendations and everyone debated which was the best of the three.
