I went there a couple weeks ago with 5 friends. I was carded before entrance. I had a driver's license that was current but was stamped, as I had recently renewed it. I was asked for the yellow paper that accompanies a license in renewal process. I didn't have it. I was refused entrance. I am 66 years old, obviously well over 21, the current age for admittance in MN. In order not to ruin the evening of my friends I drove 38 miles home to get the yellow paper. I have been a regular customer for many years and the staff knows me. I complained to the manager and was met with indifference. I won't be going back. Ridiculous.
