Tejano used to be El Chico No. 8. Now it is set to become El Corazon de Tejas.

The Cuellar family has been in the restaurant business in Oak Cliff since the 1950s. And now two members of the family are planning new restaurants, about a block from one another, in Oak Cliff.

The Cuellar family opened El Chico on West Davis near Zang in 1955. They changed the name to Tejano Restaurant in 1978, serving neon-green frozen margaritas and arguably our neighborhood’s best Tex-Mex.

Now owners John and Susan Cuellar have plans to transform this Oak Cliff institution into El Corazon de Tejas. Tejano will close after lunch on Sunday, Jan. 20, Culture Map Dallas reports, and reopen next month.

The menu at El Corazon de Tejas will include some Tejano favorites along with more chef-driven fare, and the restaurant’s interior will receive a makeover.

Tejano currently is the lone Dallas restaurant in the Cuellar family. But  not for long.

Two Cuellar sisters, Alycen Cuellar and Adrien Cuellar-McGuire are planning a new restaurant with their mom, Marcia Cuellar. They have leased the building adjacent to IndieGenius, at 409 N. Zang, according to the Dallas Morning News.

The new restaurant, The Local Oak, will have Tex-Mex, “chicken-fried steak, burgers, salads, soups, vegetable dishes and more,” according to the News.
