Three brackets, and knowing which one you're in is most of the skill. A warung plate with a drink is about IDR 25,000–50,000. A tourist-facing café charges IDR 65,000–120,000 for a smoothie bowl, IDR 75,000–130,000 for avocado toast and IDR 45,000–65,000 for a flat white. Mid-range meals land at IDR 70,000–120,000 and fine-dining mains at IDR 200,000–600,000 (Unfold Bali, June 2026). It puts the gap between eating locally and on a tourist strip at three to five times, often for the same dish.
Numbeo's Bali-wide index agrees closely enough to be useful. Updated 5 September 2026 from 331 entries by 38 contributors, it gives IDR 50,000 for an inexpensive meal, about IDR 529,000 for a mid-range three-course dinner for two, IDR 43,730 for a half-litre of domestic draught and IDR 40,174 for a cappuccino. A cappuccino that costs most of a warung lunch isn't a data error. It's the shape of the place.
Two venues here publish enough to make the gap concrete. Motel Mexicola lists tacos at IDR 60,000–65,000 each and a classic margarita at IDR 170,000. Waroeng Cabe Cabean on Nakula, a few streets inland, does nasi campur with a soup for IDR 30,000 on FINNS' figures. That's two full plates of local food for one taco. It isn't an argument against the taco, just for knowing what you chose.
Then check whether the menu is priced net or plus-plus. The gap is 17% and it shows up at the till. Restaurant tax is set locally and capped at 10% of the tax base under Article 40 of the national law on local taxes and levies. The service charge, usually 5% to 7%, is set by the restaurant. Neither line is a tip and neither is optional. Sisterfields states 10% tax plus 7% service. Motel Mexicola prints 10% plus 7%, rising to 15% tax plus 7% service after 10.30pm. We couldn't confirm what covers that higher late rate, since it exceeds the 10% ceiling, so take it as the menu's stated rate and no more. Warungs generally quote the price you pay, and Warung Leka-Leka says its prices are nett. Carry cash, because plenty take nothing else.
