Quick Trip Into Town - Need Some CH Suggestions

I'm coming into town for the weekend for a kids basketball tourney and would like your suggestions on a few spots to visit.

I've been to Shwartz's and have always enjoyed it. I plan on bringing a brisket back to Toronto with me, to steam later. Thoughts on taking my kids to Snowdons or Lesters instead? Are they really any better than Schwartz's?

I'm going to return to my youth and take the kids to the Bar B Barn. Is it still worth the trip? Lastly, any suggestions on classic Montreal food joints that my adventurous kids might like?
