Using data envelopment analysis(DEA), this study analyzed management efficiency of 5 Korean family restaurants: VIPS. TGIF, Bennigans, Sizzler, Tony Romas. Data were collected from the 2009 Korean Food Industry Annual Report. and from the five companies. Total sales were employed as the output variable, while year-on-year rate, and number of shops were considered as the input variables. DEA results show that TGIF was the most efficient family restaurant among the five restaurants. It was followed by Bennigans, Tony Romas, Sizzler, and VIPS. Particularly, even though the total sales of TGIF was only 40% of VIPS and the number of TGIF' shops(40) was far fewer than VIPS(90), TGIF's management efficiency was .22 point higher than that of VIPS. Several suggestions were made to improve the management efficiency of family restaurants.
