During the last 30 years, Houston has blossomed and grown into a melting pot of wonderful, tastefully diverse food. Bryan Caswell maps out a possible day of food fun in an article on eatery.com while he calls out people for not taking a look at all the city has to offer. But sshhh...don't tell the rest of the world or they will want to live here too.
Yes, you have to have a car since our public transportation sucks but you can spend a day and not go 20 miles and have a great meal. The next day, pick a different part of town and hit every hole in wall joint you see. That's where you are going to find really awesome food. Granted in some places you may need an interpreter. Along with diversity comes a few language barriers, spanish, indian, vietnamese and chinese to name a few and that's just in my neighborhood.
