I actually like the layout of the site. I like how the user navigates on the left pane and the information updates on the right (pretty standard--but that's good)...however, the left pane would be much improved with some uniformity--when you select a button on the left, the whole list changes order and location...if the buttons all stay in place (or at least close...shifting buttons down is fine, but sometimes it affects the buttons on top or some buttons just flat out disappear) and in order it would be perfect.
It sounds like you're already looking into changing the colors...I find the lime green, while easy to read, a bit a little harsh on the eyes. Regardless, I don't see much issue with the color theme you're going with. It pops without being overly obnoxious (I've seen A LOT of bad websites back when I was taking courses on it). I think if you just tone down the green a hair it will be great.
As for descriptions. I love having all the information available but I could see how people looking for information (weight, material, size, boil time...etc) could get frustrated by having to read the whole thing. Might be a good idea to list the specifications to balance this out.
Overall, I really don't think that it's a poorly designed website like the first person commented. The part about the layout on the left pane needing work is the only thing that actually irks me but it's still useable, just a bit frustrating...the rest of my comments are just nitpicking.
Just my two cents.
