AUSTIN (KXAN) — A small fire at a Torchy’s Tacos restaurant in southwest Austin isn’t expected to affect the lunch rush.

The fire started around 8:42 a.m. in the roof HVAC system of the restaurant location on 4301 W. William Cannon Dr. The Austin Fire Department says it extinguished it around 9:08 a.m. and then three units worked to remove smoke from the area.

By 10:24 a.m. fire crews left the area, and AFD says the damage was minor.

“Torchy’s reportedly will be open by lunchtime,” it wrote in a tweet. It is not know what caused the fire.
