Over the past two decades, Mesa’s Asian Business District has grown from a few scattered shops to a busy corridor, and one shopping center, Mekong Plaza, has been at the center of the growth. The former Target store, now an Asian-themed plaza full of restaurants and stores, is now joined by the H Mart across the street, Arizona International Marketplace down the road, and even plans for its own expansion. Even so, Mekong Plaza itself still has plenty of hidden corners to explore. One of them is a tiny restaurant by the food court known as Happy Bao’s.
