The Houston zoo is definitely one of the better zoos in the country. They have (as most big city's) been doing construction since I moved here a decade ago. The construction projects always seem to be for the better, the zoo has good flow and almost always showcases the animals they house. I would say that weekdays are the gem time. Not too busy. The months of December to March have some of the best visit weather. Gluten free food is available and the restrooms are pristine.
My only critique would be that it is easy to get turned around, while you always can see a sign pointing you to another animal exhibit, the front or the back of the zoo, or which direction you are sometimes a little difficult to determine without map or app.
