Many dim sum restaurants also offer plates of steamed green vegetables, roasted meats, congee and other soups. Dessert dim sum is also available and many places offer the customary egg tart. Dim sum is usually eaten as breakfast. Dim sum can be cooked by steaming and frying, among other methods. The serving sizes are usually small and normally served as three or four pieces in one dish. It is customary to order family style, sharing dishes among all members of the dining party. Because of the small portions, people can try a wide variety of food.
