As one of the first to enter the Shanghai market, its cave-like interior has impressed many diners. Founded in Beijing in 2008, the long-ago lamb skewers have grown in popularity since opening their first branch in Shanghai on Yunnan South Road in 2013, and have since opened six stores in Dahua Road, Wujiaochang and Dapuqiao.

It seems that a long time ago, there were also "darkest moments" along the way. Originally known as "Once upon a time it was just a string shop", it attracted the attention of diners with its unique interior style in the early days of its establishment: the new cave-like shop decoration is decorated with abstract historical murals from the Stone Age, Pottery Age, and Bronze Age, and the staggered lighting gives the store a strong nightclub style. It wasn't until 2015 that a large number of cross-border people set foot in the catering industry, and all kinds of new restaurants sprung up, which made it difficult for restaurants to resist. After nearly two years of exploration and reform, in 2017, the name of the store was not only changed to "Long Ago Mutton Skewers", but also its service methods were greatly adjusted, replacing the original ostentatious service with Haidilao-style meticulous service, and greatly simplifying the original menu, focusing on the mutton skewers, in order to subvert the image of the store among diners.

It has been a long time since it came out of decline, and it is still popular with diners. The store claims to carefully select lamb from the Hulunbuir grassland, using the standard skewers of "three lean and two fat" to make standard skewers, diners only need to place the meat skewers on the table equipped with an automatic electric roaster, the meat skewers will start to roast on their own, and they can be eaten until the meat changes color and browns, and the mutton skewers prepared with marinade in advance maintain the original flavor of the ingredients, and the taste is fat and thin, soft and glutinous and sweet. No additional dipping sauce is required to make it mouthwatering; Another dish that can compete with lamb skewers is the New Orleans Grilled Wings, which are also marinated in advance, and after grilling, they are charred on the outside and tender on the inside, and they are delicious, making them an authentic barbecue taste. If diners are looking for the best way to grill their skewers, they can seek the assistance of the staff who will explain in detail how long each type of skewer should be grilled to ensure a good dining experience. However, the products in the store are not without minefields, grilled seafood and vegetarian skewers are more often criticized by diners, due to the large number of diners, the quality control of ingredients is occasionally not in place, and the imbalance of marinating strength leads to the deterioration of the taste of dishes.

Excellent service is also a major element that attracted diners a long time ago: before diners step through the door, uniformed staff will take the initiative to greet diners, guide them and help them find their seats; If there is a problem in the process of grilling skewers, the waiter can also respond and provide assistance in a timely manner, and the service is in place in a timely manner; If the taste of the dishes is a little lighter, the restaurant is also equipped with a variety of dipping sauces and special dipping trays for diners to season by themselves. The fly in the ointment is that the lighting in the store is slightly dim, the background music is occasionally too noisy, and the quality of air flow during the peak dining period also decreases, making diners feel stuffy and cramped. In terms of price, the consumption in the store is slightly higher, taking mutton skewers as an example, half a dozen are 27 yuan, and roast wings are 8.7 yuan a skewer, and most dishes can be ordered one by one.
