To each their own. I was disappointed with Jacobs and Co. Went for my bday last year and ordered four or five variations (among everyone in our party) of cuts. None were that great.
I like Barbarians. Never been to Harbour Sixty. There are some great forums/threads about hunting for good steaks in Toronto if you google it.
I can see how people would like Jacobs and Co... for me, I prefer the value I get out of RC over paying more at Jacobs and Co. Not to say that Jacob's steak is worse (it's actually better), just not a great deal for the price premium. Barbarians is better.
