>Maybe provide a way to rate things by delicious-looking-ness? (You might want to think of a better word than delicious-looking-ness.) People could compete to have the most delicious-looking food on the entire site (like hotornot but without quite as much potential for ego shattering).

The app wasn't entirely appealing to me until I saw this. If you did this, I'd use it. (not sure if there are other players in this space)
