Judging by your showcase and reviews, you'll do well here no matter where you are. Some popular areas are the Galleria, the Woodlands, Westchase, Energy Corridor and the Med Center. These are on the West and North sides, Med Center is central. There's always the South side, but didn't list it as it's not as popular.
