Wondering what’s happening with the new Barnes & Noble store at Congressional Plaza? From what we hear, it’s not going to be ready until next summer at the earliest. That timing should coincide with the opening of the two new gyms — CorePower Yoga and Orangetheory Fitness — that are now under construction in the former Thomasville space right next door. The north side of Congressional Plaza has seen plenty of upheaval this year: White House Black Market, Modern Market and Baja Fresh all closed their doors in that section, while Chico’s and Lebanese Taverna (now LebTav) relocated to smaller spaces. And Baskin-Robbins, one of Congressional’s oldest tenants, will serve its final scoops this Sunday (Dec. 15th). Owners say they could no longer afford the rent.
