Chicago has many boat tours, from seeing the river from an architectural view point to dining and seeing the city from the lake at night. Both these companies are Chicago institutions and have been around for years. Both will meet your wants. Spirit of chicago will also give you a dining experience as well. You want a lake tour to see the skyline at it's best. Most river tours will take you through the locks and enter the lake, but the lake tour will take you up and down the skyline for the best view. Seeing the skyline from the lake at night is a glorious experience.
