The Houston Zoo is a great attraction and has excellent exhibits and staff. There were clearly-marked "Cool Zones" to visit air-conditioned indoor exhibits and catch a break from the heat. There are plenty of exotic animals and the themed areas feel very authentic. The current (Summer 2017) traveling exhibit they have was a lego section that had some really cool animals built with lego bricks. Many used several hundred thousand bricks in total!
