Thriftway in Southwest Portland to become Trader Joe's Grocery chain aims to add store in Southwest Portland's Garden Home Marketplace plaza. After months of speculation about a new Trader Joe's grocery store coming to the former Garden Home Thriftway site, the company has confirmed its plans to open a store in Southwest Portland. "We are very interested in bringing a store to Southwest Portland and are taking the necessary steps to make it happen," said Erin Baker, a spokesperson for Trader Joe's Company. "There are a number of things that need to happen before the store is confirmed." A liquor license application was recently posted in the window of the former Garden Home Thriftway store on Southwest Oleson Road in the Garden Home Marketplace Plaza. The notice lists "Trader Joe's Company" as the applicant.
