I was class of '09 and learned quickly down there that West Texas Tex-Mex is not like East Texas Tex-Mex. Warm hot sauce definitely caught me off guard. The best mexican food that I found when I was down there was Casa Rod in Downtown Bryan, but I'm sure there are several better places now, as that was over a decade ago, and I haven't made it back to CS since probably 2017 or 18, I can't really remember anymore.
