Many Indonesians have known Warung Bu Kris, one of foremost Indonesian restaurants established in Surabaya, East Java. Its modern concept of warong (Indonesian’s traditional food stall) , appetite-increasing menus, and yellowish-red color mottoes will be a tremendous hit for both connoisseurs and epicures. Besides, several photogenic Indonesian food pictures hung on the wall, boosting the ambiance. In most East Java cuisine, sambal penyet or spicy crushed chili paste becomes one of food staples along with a plate of rice. The chili is squeezed or smashed using a pestle served on a plate of mortar. Because of this uniqueness, no wonder if sambal penyet has crossed its region boundary outside Java Island.
