Directly next to you is a main road, face it and turn left, so that you are moving north up that road.  Just keep walking straight up that road for a while (if the cross street numbers are increasing, you're going the right way) and keep going until you cross over the railroad tracks, with Pennsylvania Station on your right.  Keep going straight for several more blocks, and after you pass West 37th Street, you're almost there.  At the north end of the block, meet me inside restaurant.
