Want to see the city's great architectural achievements or learn about the gems of Chicago's history...with Starbucks in hand? Then give these architectural and historical boat tours a try. The 90-minute rides costs $32 per adult and includes complimentary Starbucks coffee, lemonade, fresh-baked muffins and cookies.

Architectural cruises trawl the Chicago River (the Chicago Sun-Times called it "witty," and "the best architectural boat tour available in Chicago"), while historical ones set sail on Lake Michigan.

Cruises tend to run late-April through October, and depart hourly from 9 a.m.-6 p.m. in the dead of summer. Tickets for seniors cost $30, and youths 7-18 cost $18. Group tours and private charters available.
