Chile con queso is a Tex-Mex tradition dating to early 20th-century San Antonio, but the Austin version was codified at Matt's El Rancho on South Lamar. The Bob Armstrong dip was invented in 1973 when Matt Martinez Jr. made a custom plate for Texas Comptroller Bob Armstrong, building queso with a center of taco meat and guacamole. The dip became a permanent menu item by 1974 and remains the city's signature queso plate. Beyond Matt's, queso runs at Kerbey Lane, Magnolia and most Tex-Mex tables.

Tip from the editors. White American cheese (the deli-counter slab, not the orange slices) is the key. Velveeta works but is the lazy substitute; real American melts cleaner.
