Soto, or sauto, or coto is traditional Indonesian soup. Every region has its own version with different taste.
In my hometown, the most popular soto is "Soto Sokaraja". Originally it came from Sokaraja region, Banyumas district, in Central Java province. It has clear soup (other types of soto are given coconut milk) with shredded beef, bean sprouts, cabbage, and lots, lots of crackers. The thing that make it special from other Soto is the condiment, spicy peanut sauce. When it added, the flavor suddenly change. I and my family usually have it every our visit in Purwokerto, at Jalan Bank (the most famous Soto Sokaraja point where you can meet many Soto stall there).
In Yogyakarta (the city where I live now), soto is a popular breakfast dish (beside bubur ayam/chicken porridge). The taste and presentation is very different with Soto Sokaraja. It has clearer soup with refreshing sensation (due to more acidic broth). The Soto usually served with rice (differ from Soto Sokaraja that served with chunks of rice cakes) and accompanied with chicken innards' skewers (intestine, liver, and heart) and crispy tempeh. Preferably, I like it better. My mom usually make this type of Soto in my home since my childhood (she came from Solo, near Yogyakarta), and my palate grew with this taste.
There are many other tasty Sotos that you must try! Especially Soto Kudus and Coto Makassar!
