Update: Z’Tejas executives have confirmed that the restaurant chain has filed for bankruptcy for the second time in two years.

The filing, made Monday in U.S. Bankruptcy Court in Phoenix, Ariz., comes less than a week after four "underperforming" locations — including one in the Avery Ranch area — were permanently shut down.

"We plan on using this unique opportunity to give our customers what they should expect — a commitment to service, new whole-food based recipes and overall dining experience that has our customers coming back time and again," Stephen O’Connor, the company’s chief operating officer, said in a written statement. "We’re excited about the future of Z’Tejas."

Earlier: The Z’Tejas restaurant chain has shuttered four locations, including one in the Austin area.

The Avery Ranch Z’Tejas, at 10525 W. Parmer Lane, is now closed, along with three locations in Arizona, according to a Facebook post.

"We have begun implementing a plan to strengthen our company and focus on our strong locations in Arizona and Austin," the post said, in part. "We are excited about our future in those markets and plan on growing in both Arizona and Austin as we continue to serve all of you, our loyal guests, in our existing locations."

Z’Tejas, which was founded in Austin in 1989, filed for bankruptcy in 2015, closing its sole California location that year.

The chain emerged from bankruptcy under new ownership following an acquisition by Cornbread Ventures, a group that consists of the general partners of the Austin-based Iron Cactus restaurant chain and the Stone Group, an Austin-based commercial real estate investment company.

After the closure of the Avery Ranch Z’Tejas, there are still two locations in Austin: 9400-A Arboretum Blvd. in the Arboretum area and 1110 W. Sixth St. near downtown.
