Gado-gado  also known as Lotek is an
Indonesia salad of slightly boiled,
blanched or steamed vegetables and hard-boiled eggs, boiled
potato, fried tofu and tempeh, and lontong (rice wrapped in
a banana leaf), served with a peanut sauce dressing.

Gado-gado is widely sold in almost every part of Indonesia, with each area
having its own modifications.It is thought to have originally been a Sundanese dish, as
it is most prevalent in Western parts of Java (which includes Jakarta, Banten, and West Java provinces). The Javanese have their own slightly similar version of a vegetables-in-peanut-sauce dish called pecel which is more prevalent in Central and East Java. Gado-gado is widely available from hawkers’ carts, stalls (warung) and restaurants and hotels in Indonesia. it is also served in Indonesian-style restaurants worldwide. Though it is
customarily called a salad, the peanut sauce is a larger component of gado-gado
than is usual for the dressings in Western-style salads; the vegetables should
be well coated with it.

Some eating establishments use different mixtures of peanut sauce, such as
adding cashew nuts for taste. In Jakarta, some eating establishment boast gado-gado as their signature dish, some of which have been in business for decades and have
developed faithful clientele. Gado-Gado Boplo restaurant chain for example has
been around since 1970,while Gado-Gado Bonbin in Cikini has been around since
1960.
