This beige-walled, gray-roofed supermarket, squeezed between razor wire-rimmed industrial warehouses and North Hollywood train tracks, isn’t much to look at. The name, Pacific Coast Food, fails to hint at what one may find inside: a nirvana of edible nostalgia for those who grew up in the Soviet Union and Communist Eastern Bloc. Colloquially, it’s known as the “Russian Costco,” after the American wholesale giant, and a more fitting name for the aisles upon aisles of snacks and mainstays coming from Eastern Europe, Central Asia and the Caucasus region. The business was initially opened as a wholesaler in 2010 with San Fernando Valley’s Slavic, Baltic and Western-and-Central Asian communities in mind; notably Studio City’s huge Russian enclave and the Armenian strongholds of North Hollywood and Glendale.
