Key: Vegetarian friendliness

Many restaurants do not have a good selection of vegetarian options. Eating vegetarian is often the quickest way to minimize the ecological footprint of any given meal, since it means eating "lower" on the food chain than eating meat.

• Does the restaurant serve meat? If so, does the menu point out vegetarian options, or have more than one option for a full course vegetarian meal?
  
• Are the vegetarian options only a meat-substitute, or how well is vegetarian integrated into the menu? Do there seem to be enough variety of vegetarian options (generally more than two choices for a dinner, say)?
  
• Can substitutions be made (comfortably), for not consuming meat? Is the restaurant staff friendly and open about offering such substitutions?
