If I opened a hair salon, I can think of many names I might feel like calling it. I might call it Walter's Wondrous World of... Hair. Regardless, I would include *some* reference to 'hair' in there.
Saturn Club is a hair salon. It took me a couple of months to figure this one out - my friends would tell me they were going there, and I would always be thinking "hmm, I didn't know they were into strange clubs".
Since it's right next to the Penn campus, most patrons are students. They regularly advertise and offer discounts to students and pretty much anyone who lives in the area, so it can be a good deal. Regarding the actual quality of their cuts, I've seen a couple of my friends before and after, and I think an entirely respectable job was done.
(I realize that for some people, 'entirely respectable' is not what they want their hair to become. still.)
