There are a few different dining options but the lines can get long and the cost can add up. Instead, pack your own snacks and eat at the tables down near the Polar Play Zone. While you eat, you can watch dolphins and whales swim by and feel like you're underwater.
There are a lot of animals in a lot of different exhibits at Shedd. Your visit can be overwhelming, especially if you're wrangling a couple of kids and a stroller. Take advantage of the free days and choose what you want to see on each visit. Try planning ahead by making a theme for each visit, like a trip to see all those new babies.
