What sets Fullerton apart is its position next to Anaheim, Placentia, and Brea. Anaheim in particular is a much larger city, and its gravitational pull means Fullerton businesses often compete with a neighbor that has greater name recognition and foot traffic. That dynamic matters most for restaurants and retail, where proximity to Anaheim's tourist and entertainment draws can either help or hurt.
Before investing in marketing, a Fullerton business owner should decide whether to lean into the city's identity or try to capture spillover from Anaheim. Those are different strategies with different costs, and trying both at once usually means doing neither well.
