This week marks the closing of two Italian restaurants off Rockville Pike: Fine-dining fixture Brio Tuscan Grille, which lasted five years, and fast-casual pizza joint Pie 360, which didn’t even make it to five months. Brio, one of the original tenants at North Bethesda Market, was a popular spot for large parties but had trouble filling so many tables on a day-to-day basis. Pie 360, a short-lived experiment from the Coal Fire pizza chain, had been one of the first restaurants to open at the new Galvan complex off Twinbrook Parkway. Pie 360 also closed its seven-month-old location on D.C.’s K Street.
