Well, my usual workflow is ACR...not much in there unless some highlights need recovery (not much in this, I reckon). Then in Photoshop I ran a little Colour Efex Brilliance/Warmth filter (only a tad). Then Topaz denoise (only a smidge) then Silver Efex (can't remember the preset, but I also slide some sliders to move away from the preset settings - but only a smidge). Then sharpen in Photoshop using Unsharp Mask (usually 150 at 2.2, but adjusted as needed).
That's it. I may add a small vignette, hardly any at all, but just enough to help the main part of the picture pop a little.
