If you drove past the corner of Dobson Road and Main Street last November, you might have caught the ribbon-cutting: city officials, a developer named Peter Quach, and a crowd celebrating the finish of a $10 million, 32,000-square-foot addition to Mekong Plaza, the anchor of Mesa's Asian District. Twelve new businesses were announced that day. Nine months later, in the middle of August, not all twelve are actually running.
That gap between announcement and reality isn't a knock on the plaza. It's just the shape this particular expansion has taken, and if you're planning a trip based on something you read back in December or January, you should know which businesses are worth the drive right now and which ones are still catching up to their own press release.
Two tenants have been serving customers since the expansion's debut: Haidilao Hot Pot and Miniso. Haidilao is a Sichuan hot pot chain that started in China in 1994 and has grown into one of the most recognized hot pot brands in the world. The Mesa location was its first in Arizona. Miniso, a Chinese retailer built around impulse-buy plushies, cosmetics, and gadgets, opened alongside it.
Those two have had the run of the new wing since November 2025, which means they're the safest bet if you want to walk in without checking hours first.
Everything else has moved slower than the original timeline suggested, and Udon Shin is the clearest example. This is a Tokyo noodle shop known for lines wrapping around the block and a carbonara udon that built a following online before the restaurant ever left Japan. Coverage from early January pegged the opening for "early this year." Instead, Udon Shin didn't hold its grand opening until noon on Saturday, May 23, 2026, more than four months past that early estimate.
Development manager Drew Burtoni had already explained why the timeline kept slipping. The plaza broke ground on the expansion in July 2022 with the project expected to take about a year. Construction setbacks stretched that into a three-year build. When the shell was finally finished last November, his read on what the new tenants would bring was simple: "It's gonna add new flavors, it's gonna add new experiences."
That pattern matters beyond one noodle shop. As of the most recent restaurant-by-restaurant rundown from Phoenix New Times, three more additions, ANH (a build-your-own Vietnamese bowl concept), Hong Kong Cafe, and Mama Lu's Dumpling House (the latter two sharing one corner space), were still listed as targeting a summer 2026 opening. We're now solidly inside that window. Some may already be serving food by the time you read this. Others may still be a few weeks out, the same way "early 2026" turned into late May for Udon Shin.
If you're planning a special trip rather than a casual stop, a quick check saves you a wasted drive:
None of this is a criticism of the plaza. A staggered build-out across a dozen tenants, several of them opening their first Arizona or first U.S. location, is normal. It's just not how the initial coverage framed it, and treating a November press event as the finish line will send you to a locked storefront more often than you'd expect.
Mekong Plaza didn't appear out of nowhere. The building started as a former Target store, remodeled starting in 2006, and opened in 2008 with fewer than ten Asian-owned businesses inside. The city didn't formally designate the surrounding corridor as the Asian District until 2020, adding monument signage and murals along a stretch that runs about 1.5 miles down Dobson Road between Main Street and Broadway Road, encompassing roughly 100 Asian-owned businesses today.
The plaza itself has grown from that original handful of tenants to 29 businesses in the older section plus the new wing, and it now shares its corner with H Mart directly across the street. According to the city's Office of Economic Development, the district pulled in 6.9 million visitors in 2024, with 1.7 million of them coming from outside the immediate market, some from as far as Yuma and Flagstaff. That's not a neighborhood shopping strip. It's a regional draw that happens to sit inside Mesa city limits, which is part of why the expansion got a mayor and a city councilmember at the ribbon-cutting instead of just a store manager.
If you want hot pot or a bowl of carbonara udon that people fly to Tokyo for, Mekong Plaza already delivers both, no waiting required. If you're chasing the dessert counters, the arcade, or the newer Vietnamese and Chinese concepts still finishing their build-out, give the plaza a call first or check its posted hours before you make the drive. The expansion is real and mostly finished. It's just not finished in the single, tidy moment last November's headlines made it sound like.
For residents who've watched this corner of West Mesa evolve over the past few years, the Asian District's growth is one more sign of how much is changing in the neighborhoods around it. Celina Acosta and her team spend their days tracking exactly this kind of shift across Mesa, Chandler, Gilbert, and the rest of the Southeast Valley.

No pressure, just local knowledge from someone who pays attention to the details others skip.
