VegGuide identifies the following categories:
Vegan: For the purposes of VegGuide.Org, a restaurant is considered vegan if it is possible to randomly order anything on the menu and still have it be vegan. For example, if everything on the menu is vegan but the restaurant offers cheese for pasta dishes on request, then it should still be considered a vegan restaurant. Honey is not considered vegan. The point of defining a restaurant as vegan is to assure any vegan that they can go in and order anything they want without asking questions about the ingredients.
Vegetarian: For the purposes of this web guide, a restaurant is considered vegetarian if it does not serve animal flesh in any form.
Vegan-friendly: This categorization is far more flexible than the others, and should be influenced by the restaurant's locale. For example, in places like New York City or San Francisco, which have many vegan and vegetarian restaurants, a restaurant offering a single vegan entree would not be considered vegan-friendly. On the other hand, in a small town vegan-friendly may mean a restaurant that is willing to make pasta with marinara sauce. Particularly in regions with limited selections for vegans, even minimal vegan-friendliness is worth noting.
Vegetarian-friendly: Like vegan-friendly, the definition of this term varies by locale. A restaurant need not be vegetarian-friendly to be added to the guide, though there should be some other compelling reason for adding it if it isn't vegetarian-friendly.
Individual sites are listed separately. Categories are determined by what the vendor sells:
Restaurant - any vendor that focuses on serving food (fast food included) and has its own tables is considered a restaurant.
Coffee/Tea/Juice - a vendor that focuses on serving non-alcoholic drinks.
Bar - a vendor that focuses on serving alcoholic drinks.
Food Court or Street Vendor - a vendor at a food court or on a street.
Grocery/Bakery/Deli - a vendor that focuses on selling food ingredients for people to prepare themselves, or bakery/deli goods.
Caterer - a vendor that provides complete meals for people or groups of people. Note that a "personal chef" service would be considered a caterer as well.
General Store - vendors that sell non-food products, like clothing, shoes, household products, etc.

Other - use this category for vendors that don't fit elsewhere. In particular, this is intended for services like salons, cleaning services, nutritionists, etc.
