Laodaowai used to be the poorest part in Harbin. A century ago there were only two districts in Harbin, east (Daoli, "Dao" means Avenue, and "Li" means inside.) and west (Daowai, "wai" means outside). The rich expats lived in the east part, and the poor locals lived in the west part. In the early 1920s, some Chinese businessmen started their business in the area. The constructions they built around that period were combined with Chinese elements, such as crane and peony designs, and baroque styles, and form a unique "Chinese Baroque" architectural style. In 2014, the government renewed the area and now it is a tourist site.
Nowadays, Laodaowai ("lao" means old.) is an area for one to experience "local's" lives (that means the unique architectural style, and food, food, food, food, and food). The area is vaguely defined within Shengping St 升平街 (north), Jingyang St 景阳街 (west), Nanxun St 南勋街 (south), and Nanershi St 南二十街道 (east). If you are confused for where to start with, at Jingyang St, in between Nanxun St and Jingyu St 靖宇街, there is a later-made entrance for the LaoDaoWai area. Start from there and walk to the east, and you will see all the small streets cross one another. There are many doors (locals call them "MenDong" 门洞), which from the first sight might look like private property, in between small stores. Walk through the doors and you will reach the garden inside and the next street.
There are countless snack bars and restaurants in the area, and they are a main attraction. Keep in mind the snack bars are by Chinese definition, and many are small with few tables. They are the taste of Harbin and very popular. But in case you expect western styles (air condition, waitors speak/menu in your native languages, etc.), do not bother to go. Also if you are one of those count calories for every bite, do not go either, since watching others eating while you cannot eat is unhealthy.
Some of the popular nosheries are (from west to east):
Zhang's Stuffed Bun 张包铺 at the cross of Nanxun St and Naner St 南二街. Most popular dishes are rib buns 排骨包, tofu bun 豆腐包. At its busy time expect to share table with others.
Li's Grilled Meat 李家扒肉馆 at No.25 BeiDaLiuDao St 北大六道街 is for meat lover. Feel how the pork melts inside your mouth.
Nanbashun 南八顺 at Nanba St 南八街. Similar with hot pot. At Nanba St there is also a good pancake store. You can schedule your next on diet period after the visit.
LaoRenYi Restaurant 清真老仁义饭店 with several branches is an old and popular halal restaurant. Must try includes steamed dumplings.
At Shiliudao St 十六道街 there is an old market, with BBQ insects.
中央大街 Zhōngyāng Dàjiē; lit. Central Avenue
This cobblestone lined street is a pedestrian only street that could serve as a perfect remnant of the bustling international business activities at the turn of the 20th century. The 1.4-km long street is a veritable museum of European architectural styles, including Baroque and Byzantine façades, Jewish architectural wonders, a Russian restaurant, French fashion houses (Fake Chinese Brands), American snack food outlets (Mcdonalds and KFC and a Chinese owned "American Bar"), and a Japanese restaurant. In winter, one can walk out onto the ice or take a dog sledge or horse sledge ride. It is the prettiest site in Harbin as far as the city itself is concerned, however, if you go mid-day during the weekend be prepared to push through the crowds.
冰雪大世界
A magical kingdom built with 400,000 cubic meters of ice and snow. Highlights include the 500-meter super ice slide, the Snowflake Ferris Wheel, and the Asian同心 Main Tower. Lights turn on around 16:00-16:30, creating a dreamlike atmosphere.
松花江铁路桥
Built in 1900, this was the first bridge across the Songhua River in Harbin and served the railway system for over 100 years. In 2016, with the opening of a new bridge nearby, it was converted into a pedestrian bridge. It offers excellent views of the river and the city skyline.
圣索非亚教堂 Shèngsuǒfēiyà Jiàotáng
One of the few still standing Orthodox churches in the city. It is now converted into a Harbin Museum of Architecture. Inside there are exhibitions of many photographs from old times. Definitely worth going into, however, if you are used to European Churches do not expect the quality.
哈尔滨犹太新会堂 Hā'ěrbīn Yóutài Xīnhuìtáng
Has been restored and contains an impressive collection detailing the history of Jews in Harbin. There were 20,000 at one point and the synagogue is well worth a visit. Further up Tong Jiang Jie is the old synagogue that is now a youth hostel and cafe, with the old Jewish school next door -both worth a detour to look at from the outside.
极乐寺 Jílèsì
Large and active Buddhist temple.
