Yeah I was heading to downtown flushing today anyway, and I wanted to do wilsoneidritch a solid, since he his reviews hipped me to more than one of my favorites (and away from bad spots). But just from the outside alone it looked too legit, BIG sign saying "Leisure paradise spa." That was the big warning sign.
Then while I was walking down the block two asian women parked outside the shop, they're body language suggested that they were LOOKING for the place not working there.
All these things together suggested to me that it was a legit shop.
