Esquilino around Piazza Vittorio has the best cheap international food in Rome! Chinese supermarkets sell proper ingredients, Bangladeshi restaurants do amazing curry for €8-12, Filipino places have real lumpia and adobo.

New Asia market at Via Principe Amedeo has everything. Himalaya's Kashmir for Pakistani food. Hang Zhou for hand-pulled noodles. Romans from immigrant families eat here, not tourists.

About 20 minutes from Termini and food costs drop 50% while quality goes up. Perfect lunch break from sightseeing!
