Converting to black and white in post is the first step in my workflow for this kind of image. I then tweak the tones from there. Post processing usually means playing with the contrast, highlights, shadows, blacks and whites sliders to get the look that you want. Don't forget to straighten your images and check the edges of the frame carefully - small slithers of light or dark can really draw the eye where you do not want it to go when going for a high contrast look.
