Vegetarian
Unless you've got an odd fascination with potatoes and cabbage, you probably won't find Estonia to be a very vegetarian-friendly country. There are no specifically vegetarian restaurants, and elsewhere it's hard to find anything that doesn't involve the ever-present pork chop. Your best bet is to go the ethnic food route. Indian, Thai and Chinese restaurants usually have vegetarian sections, and Italian/Pizza restaurants can always make something without meat. Beware that soups and salads can surprise you with their ingredients, so if you're strict, ask before ordering.
