This company runs a 90-minute tour of architecture along the Chicago River, as well as specialty cruises like the St. Patrick's Day river-dyeing tour and live jazz cruises. The atmosphere is more upscale-educational than party-hearty, with knowledgeable guides who make no attempt to double as stand-up comedians. The price includes coffee (Starbucks, no less), soft drinks, cookies, and muffins. For tickets, call or stop by the company's ticket office on the lower level on the east end of River East Plaza. Advance reservations are recommended.
