In order to obtain characteristics of spatial distribution of restaurants in built-up area of Chuxiong city, the paper used average center, median center, center element, standard distance, direction distribution, k-means clustering method and buffer analysis to analyze it, then these conclusions could be drawn as follows. (1) The positions of the average center, median center and center element were located in the west of lucheng north road, north of lucheng west road, east of longhui road, and south of Zixi avenue in the old city zone. The center element was Kunming jianxin garden crossing-over bridge rice noodles shop (chuxiong shop). (2) Space distribution of restaurants in built-up area of Chuxiong city was discrete, they did not significantly concentrate in one place or a small area. (3) Direction distribution of restaurants was northwest - southeast in built-up area of Chuxiong city.
