Went to Grafton's pub for some burgers. My bike, along with my friend's bike, were locked together and to a U-rack right on Lincoln in full view of several bar patios. There was also a concert going on at a Folk Music center right where the bikes were locked. Came back after eating, and they were gone. The other bike was a small Giant racing bike for a 5'2" rider. We asked around at the patios, including two women who were dining right next to them, but no one saw anything. A report of a "large, black SUV" from one witness that had pulled up and seemed suspicious in her mind, but they didn't see the bikes taken. I think it was a professional job. The location of the incident was a safe and family-friendly area on a beautiful day. Also a good location to find lots of very expensive bikes, since it's an affluent area. My friend had bought her bike only three hours before the incident.
