Market food and one or two proper dining rooms; at this altitude the hot, heavy lunch is the meal that counts.
Mercado Central
On the corner of Bolívar and Bustillos, open 07:30–21:00, with produce and meat below and comedores and api sellers doing breakfasts and set lunches. This is the cheapest hot food in the city.
Mercado Campesino
On Calle Chuquisaca, 08:00–18:00, where produce comes in from the Potosí countryside along with cooked regional food. Bigger, rougher and much less used to visitors than the central market.
El Tenedor de Plata
Bolivian cooking on Calle Linares at the corner of Tarija, open 11:00–14:00 and 17:00–23:00, and one of the few restaurants the municipal tourism office lists by name. The obvious option once the market has closed.
Lunch is not as cheap as you expect
A market almuerzo in Potosí averaged Bs 19.11 in March 2026, second only to Santa Cruz nationally and up 59% in under two years — the sharpest rise in the country. Ch'ajchu potosino and salteñas potosinas are the local plates to ask for.
