Cleo’s Oil Bar, which opened just a year ago at Westfield Montgomery Mall, made a quiet exit last month after sales didn’t pour in as expected. Cleo’s had featured a winery-inspired layout where visitors could belly up to the bar for samples, then sip them from a seating area near the Godiva store. “Just didn’t fly,” sighs co-owner Linda Cameron, who continues to operate her original store in Annapolis. Cleo’s isn’t the only business to depart the mall in the last few weeks. Others include BCBG and Teavana, whose spaces will be taken by the expanding Apple Store (click here for more), and the restaurants Jamaican Mi Crazy and Lobster ME, which both closed on Monday along with Blaze Pizza (click here for more).
