The Gentleman's Barber Shop is a listed owner at that address. If you click on the "Tax Information" tab, they are behind in paying their taxes.
Note: there is no picture with this listing. Also, there is no lot size. I'm not really sure what the legal significance of this tax entry is. It almost seems like an on-paper 'front' of some sort.
There is, however, another business at that address, but for a different parcel number:
There is a picture of the business store-front, for Clippingdales Pet Grooming. You can see part of the store-front to the left, which is part of the Cleaners/Alternations store that you can see in full off of Google maps.
Maybe you didn't wink hard enough for them to hear you over the phone that you know the secret code to let you in? LOL Check out TBT website on the contact tab: (It also shows pic of barber shop too. Something either fishy or employees there are on a gag order by the door man. LOL)
