Don't say you weren't warned

This summer, my husband and I spent a 14 hour (7:00-21:00) layover in Amsterdam. We had never been there, and although the local aroma was a bit overwhelming, we found it a lovely place to spend the day.

Walking around, we saw lots of interesting sights and signs, including open air markets, great fruit stores, the Anne Frank House, and even the "Toby Falafel and Shoarma Restaurant and Steakhouse." (!) Toward the end of the day, we passed by an unassuming storefront with a tiny sign in the window.

I'm not sure what pulled us in closer to see what the sign said, but something did, and here it is:

We decided not to go in and see for ourselves, but we're assuming it's a haircut place. That's seems possibly logical, right? If anyone is in, or has been in Amsterdam and would like to provide extra information, please don't hesitate to update us all...
