• Google Places teamed up with 312 Dining Diva and Uber car service for the first-ever Keepin' It Classy Crawl on Saturday.
• Through a contest, 12 guests won seats on the "underground" drinking-and-dining tour, which took them to three upscale hot spots in the city. They had no idea where they were going until they arrived at each destination.
