SOS wanted good TEX MEX around the Columbus, GA
Welcome to the site! A posting suggestion: this isn't an "Ask the Experts" site; that is, nobody's on payroll to throw tip after tip at you. Rather, we're EXCHANGING information. And enjoying each other's company (this isn't just information, it's also entertainment).
So rather than lob three terse cookie-cutter questions onto the table, you'll probably have better luck cultivating relationships. Talk about the good stuff you HAVE found around Columbus Georgia (or anywhere else...on the appropriate message board). Tell others in Columbus to come onto the board and fire up some Columbus talk that might smoke out some other locals (discussion ignites more/wider discussion; happens every time). In some way show us some kind of human face so that people are inspired to take time out of busy schedules to talk with you. And if you do get tips, talk back, don't just gobble and run.
I'm not reprimanding you, just trying to help you get more of the info you're looking for.
