Qianjude Peking Duck Restaurant
Famous for duck of course, but has many other delicious entrees.
Dirty Street
This is not so much a restaurant as it is a dirty street where they sell barbecue and other foods 24 hours a day. In daylight hours it doubles as a spice market, at night there are more food options, and after midnight it is the best option for late-night meals in all of Luoyang though the city does have a few all-night McDonalds [Shanghai Shichuang], a 24 hour KFC [Wangfujing], and a steak restaurant that never closes [xinduhui] as well as various street vendors. The barbecue here is not the best in Luoyang, but it is better than what you'd find in many other cities. Adventurous eating is recommended: local favorites are sheep eyes, kidneys, and testicles. Throughout the day a large number of people eat here so the meat is generally very fresh, and the meat is cooked over an open flame so don't worry about food poisoning, but it's essentially a dirty street where drunk people go to eat spicy, greasy, salty food before they go home. Awesome food. Nobody speaks English here, but the vendors are accustomed to foreigners so just point at what you want and they will cook it for you.
