If you're looking to cook, check out two posts on the Sarah Says blog where she made stock from crab shells and then used the stock in vegetable risotto. That's a great way to get flavor from something you would otherwise throw away.
If you're just looking to eat, get some advice from the Swim-Run-Write blog where Mo tested cheesesteaks head-to-head. She pitted Simmies Arirang Hill versus Philly's Best Pizza & Subs. I have never been to either, and I have never even heard of Simmies before. Go see which one won. (Or check out all of the S-R-W food posts.)
