Krispy Kreme opened their first store in the Twin Cities in April of my senior year of HS. For the first month or so, the lines to get donuts were off-the-wall crazy, including at 12:30 AM on a Saturday night in which it had been snowing hard all day (yes, it snows in April).
The buzz wore off quickly. They were totally out of the market in less than 3 years.
Their donuts were okay. Kwik Trip makes better glazed donuts.
