My husband and I are keeping my friend's 5 year old son this weekend while they go out of town. We want to show him a really good time, but are cluesless about the Chicago kid scene as we don't have kids of our own. Can anyone suggest a fun restaurant for us that is somewhere near the Gold Coast? We are willing to trave a bit, but not too far. He is a fairly adventuresome eater, but also loves pizza, burgers, etc. Any help would be greatly appreciated!
