Because the Tungshan stop is under the operation of Uni-President Group, the group was able to pool into a small area all of their subsidiary companies, including Starbucks, 7-Eleven, Semeur de Pain bakery, and 21st Century Quick Service Restaurants; anything you want, you can find it there. On the second floor is a restaurant set up by Chi Mei Frozen Food, part of Tainan's other major business group.
因為東山是由台南在地企業統一集團所標下，挾帶統一旗下各個子公司的龐大優勢，知名的 starbucks 咖啡、7-11 和聖娜多堡麵包、21 世紀炸雞等，在這裡都可以找得到；至於東山站的二樓餐廳則是由台南另一在地龍頭廠商──奇美食品所設立。
