Cancun Mexican Restaurant in downtown New Braunfels could reopen more than two years after the roof caved in from a late-night fire that destroyed the building. Cancun, which specialized in Tex-Mex staples and Mexican seafood, was a popular lunch and dinner spot for 17 years before the Nov. 14 fire at 636 S. Seguin Ave. The restaurant also attracted a late-night dinner crowd of workers from Mexico.
