Sate is believed to have originated in Java, but has spread to almost anywhere in Indonesia, where it has become a national dish. It is also popular in many other Southeast Asian countries including Philippines, Thailand, Malaysia, Singapore and Vietnam. A key feature of Thai satay is the inclusion of pork as a meat option, and Thai-style peanut sauce. Meanwhile, Indonesian satay is often served with kecap manis – a sweet soy sauce, and is often accompanied with lontong, a type of rice cake. In Indonesia, the diversity of the  Indonesian cuisine has produced a wide variety of sate. It is popular as street food.  And it can be obtained from a travelling sate vendor, from a street-side tent-restaurant, in an upper-class restaurant, or at traditional celebration feasts.
