In a word... solid.
I happened to be in Toronto for work this past weekend, and had a dinner at Ruth's Chris. We were in the private dining room next to the bar and that was great. Our waiter was a little brusque, but I would assume that is not the norm.
I had the 22 oz bone-in ribeye, at medium rare. It was pretty good. Now I won't call it amazing, but it was a solid 8/10. Also had the mashed 'taters and big asparagus. Also had the mixed berries for desert, that was very nice.
We hung out at the bar later and that was a lot of fun, Frazer and Melissa were fun people.
