We took the Upper King St. tour with Guilds yesterday. It was fantastic. Guilds, having grown up here and having an endearing personality, has an edge over other tour guides. He can speak about the area from his own experiences and from that of local people he knows personally.
The food on the tour was tasty, and I enjoyed experiencing the restaurants, but even more I loved where he took us and the fascinating history that he presented. The highlight for me was visiting a private Jewish cemetery.
The tour is also in an area that I wouldn't normally walk around on my own and, where I would not have noticed the details that he pointed out.
