The Cleveland zoo is really a very good zoo. It's harder in the winter because some of the animals are indoors and a lot of the food stands are closed. But in the summer, there's a good variety of foods to eat and animals to see. The only issue is that some parts of the zoo don't connect to the others, so you can't go up one path and straight over to another area... you have to go back down to the center starting location. However, they offer a tram for you to hop on to make your travel to and from those areas a lot easier. And the zoo is really very inexpensive, so it's totally worth spending a day there!
