Argentum , a limited-service restaurant in Pioneer Square, is newly licensed and flipped to open on June 29, 2026. It's an Argentine coffee shop and bakery in a corner of the century-old New England Building in Pioneer Square, open since August 1, 2026. The counter runs on coffee, medialunas, and sándwiches de miga, the crustless layered sandwiches that anchor a café menu in Argentina. The concept was born in Córdoba and carried over to Seattle. Newly licensed spots often soft-open first, so check their listing or call ahead before you go.
