The Dallas zoo size is perfect to explore for half a day and see all the exhibits without worrying about missing anything. There is a children's carousel with lots of animals to ride, an enclosed aviary to enjoy birds in, a beer garden for adults, a dedicated children's petting zoo, an AWESOME giraffe feeding station, a small nature trail, and many other enjoyable activities.
My favorite parts of the zoo included the gorilla enclosure, which was very large and expansive. It very much resembled the hilly and mountainous habitat that they would naturally be found living in.
There were also dedicated animal shows every half hour that showcased a different animal every time, with trainers that had great ways to highlight the animals while incorporating the small audiences. At one show they had the turkey vulture fly inches above the kids heads, and they all loved it!
There was also a giraffe feeding station where you can spend $5 for a handful of large leafed Lettuce and hand fed the giraffes. You can touch them, feel their soft fur, and take great pictures with their heads right next to yours!
While Dallas is the smaller of the two area zoos it still offers a good value, even if you have to pay $10 for parking.
