I haven't been to a zoo since I was a small child and the Houston Zoo is a delight! They really cover it all from insects, reptiles, birds, animals of prey, lions, giraffes, gorillas and even under the sea! They even offer wheel chair and electric scooters for rent. It took about 2.5 hours to see it all. I highly recommend!
