Shoreline Sightseeing Sunset Cruise

The basics: 45-minute lake cruise, $14.
Available: 8 p.m. daily.
Departs: Navy Pier, West Boat Dock.
Features: The instruction "remain seated at all times" seems more Disneyland than pleasure cruise. Guided narration is done via a voiceover that far predates Millennium Park. Its campy tone evokes a 1950s Chicago.
Refreshments: Soft drinks, cheap wine and Budweiser. Or Bud Light.
Best for: Tourists only, who unfortunately will leave Chicago believing that the city's last great boon was Grant Park.
