England, Scotland, Ireland, Wales, France, Germany, Switzerland, Belgium and Austria are some of the countries that make up Western Europe. Cuisine varies widely from one country to the other and no one dish or one way of cooking symbolizes the entire area. The languages and religions vary greatly as well, making Western Europe more diverse and harder to define by region. Even the currency varies, as the countries of the United Kingdom, except for Ireland, have not followed suit in adopting the euro but have retained their own system.
