The Topanga (S. Calif.) retail store opened Friday morning to a huge crowd that discovered the store is 75-feet wide and is a clone of the Fifth Avenue (NYC) store. The store breaks out of the 30 or 40-foot standard space, and also expands upon the new store design that was introduced at Columbia (Md.) and Providence (RI) two weeks ago. The front of the store features a wide-open entrance, and a Fifth Avenue-like interior: wide aisles, large display tables, back-lit wall graphics, trio of bars, and stainless steel walls. The realmacgenius has posted photos of the grand opening that show what may become the new standard for Apple’s mall stores.
