So I'm a chowhound from Chicago, and I, for some reason, didn't do the proper research before heading down to visit my parents in Houston. A few members of my family don't eat meat on Saturdays (it's cultural), but we are all huge fans of authentic Mexican cuisine. I know it sounds ridiculous, but Chicago has some amazing joints, and I'm almost hoping Houston can put us to shame. Any suggestions? Anywhere in the Woodlands area and around Houston will be fine by me.
