I've been to this place I believe - somewhere on the 800 or 900 block of Royal Street - called Cuba Cafe or Habana Cafe or something like that - if we're talking about the same place. They had some gems when I went, and the guy I spoke with (owner or manager, I'd guess, but I don't know) was helpful.
He wasn't a cigar geek per se, but pointed me to stock that had been bought on auction from Christie's and was in very good shape... and volunteered the statement that much of his cuban stock was not really for a smoker - but more for novelty value of saying you smoked it. I don't think he had more than 3 or 4 boxes of things that I would even consider, and nothing that was on my "really want to try" list... I did have an RyJ Edison (I think that was the name?) from just before the embargo - and it was very good, IMO.
Not a source I would go out of my way for - but an interesting ad-hoc/one-off experience.
Cheers,
