I grew up in Houston but don't live there anymore; the membership fees are so low that my parents kept my membership alive even after I moved away! So I can work out here when I visit home. Bally's has always been a quality gym for the price, reliable but no frills. This location is nicer, airy-er and newer than the location we used to go to (Sharpstown, which was dingy and old-feeling the last time I went, but hey, it's fine for what it is). Good variety of equipment and classes, friendly staff, plenty of parking and location is easy to get to. No pool at this location and, like most (all?) Bally's, you need to bring your own towel to wipe off machines, but that's no biggie given the low price.
Pros: Location, Variety of equipment, Inexpensive
