A graduate of Le Cordon Bleu, a world-class culinary school, Linda Wang has established her own French sweets brand Cai Jia in Shanghai and has created a number of popular desserts, such as Napoleon's signature name. After gaining a foothold in Shanghai, Linda Wang from Hangzhou opened her store back to her hometown and attacked the city's high-end cake market with elegant French desserts.

Napoleon cake is a French dessert that originated in the 18th century, and is called mille-feuille in French, which means thousand leaves, so the paraphrase should be called mille-feuille cake (of course, mille-feuille cake refers to other things in China). As for why this cake is described as "Napoleon", the more reliable explanation is that this mille-feuille was invented by a chef in Naples, Italy, and is called Neapolitan puff pastry, but because the pronunciation is too similar to Napoleon, it was translated as "Napoleon" by later generations. In any case, this dessert combines the crispiness of the puff pastry with the sweetness of the cream, and is very popular with the public, and it is the star category of French sweetness. The Napoleon cake is Cai Jia's well-deserved signature, with a crispy and fluffy three-layer puff pastry, and a caramel aroma after baking; The puff pastry is filled with cheese and whipped cream, and the fresh blueberries are set off with a golden and light aroma. All Napoleons in Cai Jia's store require reservations, and there is no dine-in.

Compared to Napoleon, who was a stable performer, Hangzhou Cai Jia's lemon tart and opera house performed slightly worse, the former from the smooth taste of the creamy and sweet lemon filling, which was completely masked by the dry and hard crust underneath, and lost a lot of color. The opera house was originally a store sign, but for the style sold separately with cut pieces, the texture is hard, and there is no contrast with the cake base and the chocolate sauce on the top and bottom, and it is supposed to be a multi-layered opera house, and the taste of each part tends to be the same, which is quite disappointing.

With a reputation and location in the Kerry Centre, Cai Jia has naturally become one of the most talked-about cake shops in Hangzhou. Compared with the Shanghai store, the environment of the Hangzhou flagship store has been greatly improved, with solid wood floors, crystal chandeliers and a French-style façade, which makes people feel the romantic atmosphere of French desserts, so it is often common for a full house to be full. Although Cai Jia's level of cutting cakes has fluctuated, and the high pricing has caused many consumers to complain about its "flashiness", the mature R&D team and supply chain are difficult to find opponents in many cake shops in Hangzhou, especially French dessert shops, so it is worth recommending.
