Hi, my husband and I will be visiting Chicago in a few weeks with our 8yo son. We will be staying close to Millenium Park. We plan to be downtown for most of our one week stay. (museum park, art institute, navy pier, etc.) We will also visit Legoland and will be seeing Blue Man Group. I would love some suggestions of places to eat that are casual and kid friendly. Keep in mind our son is a pretty adventurous eater for an 8yo. We all love sushi and would like to have some good sushi at least once during our stay. We all enjoy different ethnic foods as well.
