Thank you, all, for the recommendations for Toronto sights and dining.
In our three nights sojourn, we took in The St. Lawrence Market on a Saturday, the Art Gallery of Ontario (and the Turner show, which we had missed seeing in London), the Royal Ontario Museum, the CN Tower (in the midst of a United Way event, such that it was overrun with happy people in sweat clothes who had just walked/run up the tower for charity), the Gardiner Museum, the charms of Queen's Park at sunset, and the sights of Bloor St. West (hitting Leatherfoot, Harry Rosen, and Holf Renfrew), as well as Queen St. West (my one souvenir of Toronto is a hat from Goorin Bros. - it will make it to WAYWRN, most likely on Friday). We even got out of town to see Niagara Falls Monday, which was a perfect day to see the falls. (There are photos of me sporting the fashion item given to all riders of the Maid of the Mist - essentially, a pink plastic garbage bag with a hood and armholes - but whether it makes it to these fora remains to be seen, my tolerance for comedy at my own expense having its limits.)
For eating, we indulged in the local delicacy of poutine (once is quite enough for the waistline, thank you), had dim sum at Lai Wah Heen (which wad quite good in our estimation) and at Rosewood on Spadina (which was fairly awful, truth be told), Thai food at Pai (quite nice), and we had the privilege of meeting and dining with RogerP of these fora at Bosk, which made for a delightful evening, for both the food and service, and for the company and conversation, making our last night in Toronto (Monday, 2015/11/09) memorable.
