That includes New York City Mayor Zohran Mamdani. On Monday, Mamdani announced that the city-run grocery stores he plans to open will sell food staples at a 30% discount from “the typical retail price in New York City.” Mamdani promised during his campaign that he’d open city-run grocery stores. He has now announced locations for stores in two boroughs: the Bronx and Manhattan. On SiriusXM, he said he plans to open one in each of the other three boroughs by the end of 2029.
