Thought I'd toss another tailoring option out there, Raymond's Mens Wear and Tailoring up on the north side on 137 Ave in the big row of mini malls and box stores near the St Albert Trail. The selection of suits etc there is 'meh', although methinks that's just out of necessity to appeal to your average badly dressed Edmontonian.
But the gem is his tailoring. He does exactly what you ask for, the finished work is top notch and he works very fast (and his rates are very reasonable). He's also a pretty well dressed dude by SF standards (the couple times I've gone in he's always wearing a nicely fitted glen plaid suit) which in my mind means he appreciates well tailored clothing.
Since I moved to the north end I don't feel like going all the way downtown to get work done, and this guy is certainly a great replacement (and frankly, I think he does better work then any other place I've been to).
