Kuanxin is a roast bird restaurant recommended by many Shanghai diners. In its heyday, there were three branches in Shanghai, but for various reasons, there is only one store on Ziyun Road, and the name of the store has also been changed to "Bu Xin".

Bu Xin uses roast birds and chicken sashimi as his signatures. The raw chicken comes from the local area, the ingredients are fresh, and the ingredients are handled properly, so it is very good in terms of production. Diners often mention that the chicken diaphragm is Bu Xin's best-selling item, it should be noted that the physiological structure of the chicken is not diaphragm, the so-called diaphragm is likely to be chicken neck, this part of the meat because of regular exercise, so the meat is firm and elastic, chewy. Chicken neck is a rare part and is very frequent, so diners with a special preference for rare parts are reminded to make reservations in advance. In addition to the variety of parts, chicken skewers also have a variety of combinations. Chicken green onions, garlic chicken skin, etc. are good types of skewers, and the grilled green onions and garlic have less spicy flavor and play a role in relieving greasy. The taste of the skewers is the best when it is first served, so you don't have to order too much at once, and ordering one skewer after eating is also one of the local practices.

With good production, Bu Xin basically doesn't have to worry about not having guests to patronize, so he is a little arrogant in reception at times. The interior decoration of the restaurant is simple and gray, and the ventilation is not very good, especially at night, the indoor smoke smell is relatively heavy.

There used to be a saying in Shanghai that "stubborn father, Kuanxin, and Youyi were called the three major roast bird shops in Shanghai". However, with the renewal and iteration of the catering industry, the stubborn father maintains the standard; The store address has been changed several times; With the demolition of Guyang Road, the popularity of the word of mouth gradually went downhill.
