Over the past few weeks at Westfield Montgomery mall, at least four businesses have quietly gone dark. Ivyees Everything, featuring honey-based gifts and cosmetics, is closing down after a five-month run in the Nordstrom wing. Owner Ivy Lawson, who has another store in Massachusetts, says it was too difficult to find employees who could run this location when she wasn’t on site. This week also marks the end for the Patrizia Luca clothing boutique, which has moved around the mall at least a half-dozen times since 2015. Owner Mahmoud Nassaj says he’s tired of relocating and wants to take a break from the retail business. Also gone from the mall as of this week: Big Al’s Subs, which lasted just four months in the Dining Terrace. And the ZBounce kids’ play space has closed its longtime location in the Macy’s Home wing, but the owner tells us he’s hoping to reopen across from Forever 21.
