I believe Cloud has this exact lens too? Its great for portraits and shallow Depth of Field (due to the large aperture, as Hyoushi stated).
Almost the same. I have the 50mm 1.8.
Anyway, Cohen...
I agree with BlueTsunami on the camera suggestions. Best bet is probably a Canon XS/XSi because they're pretty much the ultimate "beginner to DSLRs cameras" (or any of the cameras in the Rebel line really, those are just the newest ones).
However, I don't think that you need to shell out a ton of money for a lens.
The Canon EF 50mm f/1.8 II will take care of the majority of your food photography needs, especially for a beginner, and
can be had for just 86 bucks at amazon.com.I have the EF 50mm 1.8. Here's some examples of my food photography that was done with that lens:




Even the kit lens that comes with the XSi (the EF-S 18-55mm f/3.5-5.6 IS lens) takes pretty good food photos.
So my suggestion, made simple and easy, is:
Canon Digital Rebel XSi 12.2 MP Digital SLR Camera KIT (with EF-S 18-55mm f/3.5-5.6 IS Lens) ($700)
Canon EF 50mm f/1.8 II lens ($86)
total = $786 and you've got yourself two lenses that are great for food photography.
