I'm at a taxi stand on Pearl Street. Got north from where you are at and you will come to a point where you can veer of northwest or go directly east and you'll want to go east.  You'll pass 1 New York Plaza almost rigth away and continue heading east (well slightly northeast at this point but it's mostly going east) passed the plaza.  You'll pass the Vietnam Veterans Plaza and you'll want to turn left at the very next intersection which only goes about a block and then you'll get to Pearl Street finally and make a right (northeast again) and you'll see the taxi stand at the next intesection on your left.
