after the restaurant launched LBS check-in service in Sina Weibo, the restaurant cooperated with Sina and settled in Sina Weibo check-in service. Sina Weibo can set up POI(PointofInterest) Page pages for different restaurants all over the country, showing the information of a restaurant in detail. Such as recommended food, discount information and so on. In 2113, the restaurant company launched its own mobile APP "China" with functions such as restaurant reservation, activity information, personal center and map search. With the explosive growth of WeChat, restaurant companies have multiple public accounts on WeChat, and they are actively cooperating with Tencent on the periphery of WeChat public accounts, such as WeChat payment. It is not difficult to find out from the process of self-built O2O by catering enterprises that this kind of online to offline is beneficial for catering enterprises to carry out more in-depth cooperation according to actual needs and can be customized for development.

however, this model also exposes some disadvantages, that is, the development cost is high, and the maintenance cost increases because of the scattered resources. This model is suitable for well-funded brand enterprises. Through this platform, restaurant enterprises set up their own mobile stores (APP) by themselves, and automatically generated mobile business cards (mobile websites) and micro-websites, all of which illustrated the comfortable environment of noodle restaurants, exquisite dishes promotion, promotion of daily special dishes, etc. Among them, the location reservation service was realized through one-click direct dialing of mobile business cards and online reservation functions of mobile stores and micro-websites. In addition, through this platform, members can be effectively managed and sent SMS/MMS, and social media marketing can be carried out by using WeChat/Weibo based on O2O QR code application. As can be seen from the case, this kind of online to offline is conducive to the aggregation of scattered mobile marketing methods, which is convenient for the management and maintenance of restaurant enterprises and enables them to quickly lay out O2O. In addition, the operating cost is low (but the cost of developing an APP independently is also very high. For details, please refer to Ma Haixiang's blog "How much is the cost of making and developing App application software"). However, the disadvantage of this model is that it is not suitable for customized in-depth cooperation, and this model is suitable for small and medium-sized enterprises with short funds. ?
