First pass over the file was for highlight, shadow and neutral. Shadow went in the darkest area, highlight in the icing (do Amercians call it "frosting"?) on one of the cakes in the lower left. Neutral was a tricky one - there's all sorts of colours in this image, many of which shouldn't be there! Neutrals in the more obvious white areas pulled the curves all over, so I ended up with a single neutral on one of the paper wrappers on the top shelf.
Second pass was for contrast. The image is taken through a window at a slight angle, so there's more contrast in the left side than in the right. So I created a horizontal gradient mask and pulled a S in the L channel. This increases contrast on the right side without overdoing it on the left.
Third pass was to open the darkest shadows. As much as I like CM, I've found the best way of doing this is to run CS2's highlight/shadow filter in Lab mode. This brings out detail in the very bottom shelf.
Fourth pass was for saturation. After a gentle general tweak upwards, the only bit that really needed a significant boost was the M'n'Ms in the lower right. I used an isolated bump in the S curve - anything else made the wooden window frame look distractingly yellow.
Finally I sharpened the L channel.
There's still more that could be done with it. It's still lighter on the right than on the left. The icing in the top right is slightly magenta; most of the rest is slightly blue. I guess that's from assorted reflections and mixed lighting. Given that it's only those very bright areas that show it, I'd probably be tempted to just desaturate the extreme highlights of the image. But I've spent enough time on it already!
