清朝末期大稻埕是台灣北部的商業中心,馬關條約後為了因應日人與台灣本地的紳商階級對飲食的新要求,大稻埕興起了許多大型的餐館,而江山樓正是其中著名的佼佼者.由於江山樓本身建築物氣派,樓主吳江山雅好風流,交友廣泛,且善用商業策略加以經營,江山樓成為推廣台灣菜的重要餐廳,同時也成為紳商與統治階級社交的重要地點.許多商業及文化組織如瀛社,南友會經常於江山樓舉行例會,許多當時的名人如陳天來,杜聰明也都曾於江山樓宴請朋友.當日本裕仁皇太子訪台時,他的餐飲皆由江山樓負責,可見江山樓之重要,此論文將從不同的角度探討江山樓的重要性及其與當時紳商的關係,藉此提供台灣研究一個新的切入角度. / Dadaocheng was the business center in northern Taiwan in the late Qing Dynasty. After the Shimonoseki Treaty, many large restaurants were built in Dadaocheng to meet the new demands of the Taiwanese gentry as well as Japanese officials and businessmen. Under Japanese rule, businessmen were the main component of the Taiwanese gentry. The new gentry class required a place to socialize with each other as well as with Japanese officials. Large restaurants like the Jiangshanlou were established at their request and profitable information and favors were exchanged. The gentry frequented Jiangshanlou because the restaurant was outstanding in various ways, including the magnificence of its building, its refined cuisine, and the good management of the owner, Wu Jiangshan. Wu invited the gentry to leave their literary works in the restaurant thereby creating a chic-image for Jiangshanlou so that it could attract customers of the upper social class. Many business and cultural associations such as the Yingshe and the Nanyouhui chose this restaurant to hold meetings and banquets; many famous members of the gentry such as Chen Tianlai and Du Congming held welcome parties and weddings in Jiangshanlou, too. In human society, an individual’s culinary habits and means are a good reflection and measurement of their position in that society and this was certainly true of Taiwanese society under Japanese rule. After the 1920s, Jiangshanlou represented the highest level of culinary standards in Taiwan. The popularity and importance of Jiangshanlou can be proved by the fact that when the Japanese Prince Imperial, Hirohito, the future emperor of Japan, visited Taiwan, the restaurant was designated to serve his meals. This thesis will examine the Jiangshanlou from various aspects as well as its relationship with the gentry.
