Yanyan is a very hot Japanese restaurant in Shenzhen, especially during dinner time, when the supply of tables exceeds the demand. The Rock Salt Kerry store is located in the central business district of Futian, where there is an endless stream of urban people who come here to discuss business, date, and get together. Soon, Yanyan opened a second branch in Yifang City, Bao'an.

The Rock Salt Restaurant is dominated by teppanyaki, and most of the seats in the restaurant are designed around iron plates, and there is a row of fresh food counters that can seat about 10 people. The evening market of rock salt is mainly a set menu, which can also be a la carte, and the price of the set menu ranges from 350 yuan to 3,000 yuan, and the per capita consumption is very high. Many of Rock Salt's teppanyaki chefs are from Hong Kong, and the teppanyaki cooking skills are favored by a considerable number of diners, but at the peak of the meal, the chefs are busy serving dishes, and it is difficult to appreciate the fancy teppanyaki.

The freshness of the ingredients in rock salt is worth affirming, especially most of the high-quality seafood ingredients, and the taste will not be too bad without too much processing. The restaurant is fashionable and luxurious, with a strong sense of urbanity, and the music in the restaurant is fast-paced jazz, coupled with the sound of iron plates and talking, and the dining environment is very noisy. In addition, the service cannot keep up during peak hours, the rhythm of serving is chaotic, and the response is not timely enough, which is often criticized by diners.
