Mr. Cheng’s restaurants source many of their ingredients from Japan, including fresh fish, rice, sake, shochu (a Japanese spirit), and seasonings. The approach to ingredients remains the same as ever. In fact, they can now bring in an even greater variety of ingredients, thanks to their growing number of customers. Mr. Cheng’s creative touches are added throughout the seasonal menu items that rotate in and out every day. The devotion to selecting ingredients here is absolute, with an emphasis on providing a sense of the season, whether it’s the time of year for matsutake mushrooms or female snow crab. Ingredient news and pictures are sent out from Mr. Cheng’s personal WeChat (a social media platform that is hugely popular in China) account, so WeChat users can get the latest info on the sushi here anytime. The photos of crab and other fresh seafood that are sent out every day will arouse viewers’ appetites.
