I have very useful website for vegetarians and vegans called Happy Cow (click on the link). If you put in a zip code, it is a nice list of vegetarian restaurants and natural food stores. I think many vegetarians and vegans have trouble traveling and food that is located on the street. This can be a lifesaver!
Even if you are not vegetarian or vegan, this site can be found on the road, while the healthy choices. Vegetarian meals are often lower in calories, but the restaurants covered are, have a choice of meat. If nothing else, meeting in the list of search results, stop along the way snacks.
Let me know if you use it and you find it useful!
