Rockville’s long-awaited Trader Joe’s opened on Friday (Sept. 7th) at Travilah Square Shopping Center off Darnestown Road. The store was packed from 8 a.m. on, with live music, tastings and giveaways all day long. This is the second Rockville location for Trader Joe’s, replacing the one in Gaithersburg that closed its doors this week. The look is cleaner, the aisles are wider, and there are tables outside for al fresco dining. The grocery store has been a game-changer for once-dowdy Travilah Square, which is now attracting new tenants like Cafe Rio Mexican Grill and the upcoming Flower Child.
