In conclusion, I went all directions ENSW on the main drag from the described subway exit just in case. Nothing.
Going due north from the exit on the main street was also nothing. If he meant North then West to where all the girly bars were, then I wish he would have said so. That was the last place I looked and criss crossed each side street carefully. I saw 2 more 18 and older diamond logos. Other than that. Squat.
Could have been more descriptive as to what landmark it was near. Was it high on a building, eye level, an ad, a store marker. Big or small.
For me it was a needle in a haystack.
Sorry.
