Interesting, I'm guessing places have to register on the site?
I did a 5 mile search and found nothing which was surprising since we have quite a few places with low calorie options. I did a 50 mile search and it listed a couple places. One of the places was a chain restaurant that is about 40 miles from me but the interesting thing is there is a restaurant that belongs to that chain about a mile away from me. So it seems like a good idea but be aware that it might be limited
