Pictures of braised pigs’ feet decorate the front of the store. One of the famous braised pigs’ feet restaurants in Jangchung-dong and Korea’s No. 1 braised pigs’ feet restaurant that attracts customers is Big Grandma’s House. The 1st founder, Jeon Sook-ryeol, recalled the taste of pigs' feet cooked by his mother in the 1960s and started the Big Grandmother's House. As the taste of braised pigs’ feet went viral, braised pigs’ feet restaurants were naturally created around it, and the current braised pigs’ feet Alley in Jangchung-dong was born. Since then, CEO Kim Myung-sook, the second daughter-in-law, and director Kim Song-hyun, the third granddaughter, have continued the tradition of Big Grandmother's House.
Big Grandmother's House stands out among the many braised pigs’ feet restaurants. When all the competitors raised prices, they were the only ones who maintained prices and kept customers satisfied. In addition, the restaurant quickly reflects trends by developing single-person and set menus and introducing delivery services and various promotions. This is very differentiated because most long-established stores are late in reflecting new trends.
