Meat is common, for those who can afford it, including a lot of pork. A lot of food is fried. Soy, peanut, and sunflower oils are available, but butter, vegetable oil, and pork fat are more commonly used. Some combination of rice, potatoes, bread, noodles, and bananas is included in most typical meals. Eggs, chicken, and dairy products will probably supply your main protein.
Chinese restaurants are fairly common, at least in cities and larger towns.
