Just walked in on a Friday night because I was in the area (I live in Minneapolis) but I will definitely make the trek back out to Maple Grove to tan here regularly.
It was obviously dead because it was a Friday evening, but the lady working took time to explain all the beds to me, which was extremely helpful.
The best part, since I'd never been there before, I tanned for Free! Any bed, your choice, first time is free no matter what.
The bottom line: Clean, Friendly Service, Comfortable Waiting Area, and Great Specials.
Pros: First timers tan FREE
Cons: none that I experienced
