Remember last month when we tipped you off that something big was about to happen at Congressional Plaza? Well, that rumor we told you about turned out to be true: Barnes & Noble is moving in. The bookseller will trade its longtime digs at Montrose Crossing, home to discounters like Marshall’s and Target, for a smaller space at Congressional among the posh likes of Last Call by Neiman Marcus, Saks Off 5th and The Fresh Market. Plans call for a 2020 opening next to The Container Store, where there’s plenty of space after the recent departures of Thomasville (bankrupt), White House Black Market (closed), Chico’s (relocated elsewhere in the plaza) and Lebanese Taverna (likewise). (More details on all of these changes in our Feb. 21st edition.) Barnes & Noble has been trying stay afloat in this online economy by closing many of its big-box locations (we’re looking at you, downtown Bethesda) in favor of slimmed-down stores with a carefully edited merchandise mix.
