Southlake Events to Plan for in September 2026

Three dates cluster between September 12 and 16 this month. Saturday, September 12 brings the city's 70th birthday party to Town Square. Monday, September 14 brings a restaurant opening following two earlier target dates. Wednesday, September 16 brings a one-night history exhibit. Together, they offer a snapshot of Southlake's September calendar, from civic celebrations and restaurant openings to local history.

How Civic Events and Business Openings Are Scheduled

A city-run event has a budget line, a venue reservation, and a communications team whose job is to hit the date they announced. A restaurant or retail opening has a landlord, a general contractor, a permit office, and a lease clock that only starts once the buildout is actually finished. The events and openings announced in Southlake this year illustrate how those schedules can differ.

The clearest example is Hudson House, the Vandelay Companies restaurant that's been trying to open on East Southlake Boulevard since last October. The target slid from spring 2026 to August, then to a vaguer "this fall" by mid-August, before a firm September 14 date finally stuck. Celebrate Southlake, by contrast, is a recurring civic event organized by the city.

Saturday, September 12: Celebrate Southlake

Celebrate Southlake runs from 4 to 9 p.m. at Town Square this year, and the program reads like a checklist built to be repeatable: live music, family activities, local food trucks, an anniversary light show, and free tree saplings tied to the city's 2,026 Trees in 2026 initiative.

This year's recurring Celebrate Southlake event adds a 70th-birthday theme, marking the town's incorporation in 1956.

Monday, September 14: Hudson House

Hudson House is opening at 1131 E. Southlake Boulevard, a roughly 5,000-square-foot space that will be the brand's 11th location across DFW, a lineage that started with a single neighborhood restaurant in Highland Park and has since grown into one of Vandelay Companies' defining concepts. As quoted by FSR Magazine, Hunter Pond, founder and chairman of Vandelay Companies, said:

"Southlake has the combination of energy, growth and appreciation for hospitality that we look for when entering a new neighborhood. Our goal is never simply to add another location. We want every Hudson House to feel rooted in its community from the moment it opens."

Two other openings also illustrate the range of timing announcements. Whistle Britches, a scratch-made fried chicken spot at Town Square, opened with no press release and no announced target date at all, and has quietly built a following anyway. On the opposite end, Wonder, the multi-restaurant food hall concept backing chef partners like Bobby Flay and Marcus Samuelsson, filed permits for a space on West Southlake Boulevard months ago and still has no public opening date. Wonder is also pursuing storefronts in Spring and a cluster of Houston locations, each on its own permit-driven schedule.

Wednesday, September 16: A Museum for One Night

The third event brings local history into focus. On September 16, from 5 to 7 p.m., Legends Hall inside The Marq Southlake turns into a one-night history museum for "Our Southlake: 70 Years in the Making," co-hosted by the city and the Southlake Historical Society. The exhibit pulls together photographs, oral histories, and past historical society displays to walk through how a town of a few hundred people became what it is now.

The founding detail worth knowing: on September 25, 1956, 54 residents gathered at the 1919 Carroll School and voted 30 to 24 to incorporate a new town measuring 1.62 square miles. That's 54 residents in one room, deciding the outcome by six votes. The exhibit is built around that story and the people and businesses that existed before that vote ever happened. There's no ticket; event information appears on the city's newsletter and the historical society's calendar.

Town Square Retail Openings in 2026

Several other openings and planned debuts are on the calendar. Rothy's has already opened at 307 Grand Avenue East, near Vuori. Crate & Barrel targeted an opening near Independence Day for its nearly 19,000-square-foot store at 321 State Street, and by most accounts hit close to that window. Reformation is working through a three-month renovation aimed at a fall debut at 213 Grand Avenue, and On Running is aiming for the second half of the year at 415 Grand Avenue East.

In a report by CW33, Jason Kasal, vice president and senior leasing director at Kite Realty Group, which operates Southlake Town Square, said: "Southlake Town Square continues to attract best-in-class brands that align with the lifestyle of our community." The retail and restaurant openings have different announced timelines and project details.

Planning Around the September Dates

Celebrate Southlake is scheduled for September 12, the history exhibit for September 16, and Hudson House announced an opening date of September 14 after two earlier target dates. Wonder has no publicly announced opening date.

Those are the dates to keep in view as Southlake's September events and openings unfold.
