When you eat while sitting on the matted floor, usually with your legs
crossed, and food is served on a low table kinda like a Japanese table. We called it lesehan. It is a very typical way of Jogjanese diners. I do several times in some of the lesehan diners on Malioboro
Street.
The food prices can be unreasonably marked up unless you make sure about the prices before ordering anything. The most famous lesehan diner is Terang Bulan, but you can pick just any one you want. They mostly serve similar menu, including grilled or fried chicken, dove, duck, and the special Jogja menu like gudeg and pecel lele, etc.
Eating can be disturbed by street musicians playing – mostly – popular hit songs and wouldn’t go unless you give them money or show a hand sign saying ‘no, thank you’. However, if you’re curious to hear what Indonesian songs are like, then have them play a little longer, while you can pay a little more.
