Saw this on LifeHacker today, and I just figured I'd put it up for everyone here to rate. I know I've seen some posts that consider allergens in restaurant food, so it seemed reasonable to throw it up here.

I have no idea how to rate it - I don't have allergies (that I know of) so maybe y'all can tell me if it's any good :p
