Built as a Mervyn's in 1981-1982, this store sat vacant between December 2008 and September 2011. At this time, a Cheesecake Factory became the first of three tenants to reoccupy the space. H & M was dedicated in September 2011, followed by Forever 21, which opened the following November.

A circa-2012 plan, showing the reconfigured Mervyn's space. After nearly 60 years and several expansions, HILLSDALE remained a viable retail center. It had weathered competition from SAN MATEO FASHION ISLAND (1983)...and eventually eclipsed that center (which was demolished in 1996).
