Costco has officially opened their doors. The 154,000-square-foot Costco, located the Shops at Dakota Crossing (Market Street NE at New York and South Dakota Ave) opens at 8 a.m. this morning! The Post reports that Vice President Joe Biden was even in attendance for the opening ceremony. The location will serve as the anchor store in the new retail center located in Ft. Lincoln, and be a major boom for the district from the jobs perspective. The addition of Costco comes with strict contrast to the other big box retailer making waves in DC Walmart. Consumer retail diversity is very much welcome in the District, but the purveyors often are scrutinized. Costco, which in recent news is hailed as the "Anti-Walmart" will add several hundred permanent jobs to the Distrct with this single store.
