Our favourite place for local food at unbeatable prices is Dewa Warung on Jalan Gootama (between Jln Dewi Sita & Ubud Main Rd). We call it "Big Steps Cafe" in reference to the huge concrete stairs leading up from the street to the double level eating area. The Indonesian classics of nasi campur, mee goreng & gado-gado are offered along with delicate green ferns tossed in fresh coconut, full flavoured tempe and tofu curries, and peanut satay sticks (all without MSG). Suckling pig or roast duck is available if you order in advance. Juices are big and cold and less than $1 each. Even with two main dishes, drinks and dessert it is tough to spend over $10. Tables are limited and communal, and dinner time can be busy. The toilet is a pretty rough squatter without paper so be prepared.
Waiting out a wet season deluge with a cheap and cheerful lunch.
