We ate at Alborts, the only sit down in the Zoo. It was amazing. They recommend reservations if you plan on eating after 5PM, though. It was pricey, as all the food is, but delicious and the outside atmosphere was great. A huge water fall, and all shaded by lush greenery around you. It was cool. Staff was very friendly too. I had the chicken strips from one of the counter service and they were not gross. Just like $8 for three, which is ridiculous.
