Actually a proper Manhattan is nothing like a modern Gin/Vodka Martini or a classical 20th century Martini, but is similar in some respects to a Perfect Martini due to the addition of sweet vermouth or the traditional Martinez, believed to be made with sweet vermouth. Having said that, I do like the odd Rob Roy. Some places shake deliberately to get the froth as Manhattans tend to have a signature twist in posher places. I think you're right to ask to stir instead for a classic Manhattan (especially if you're using Canadian Club or Crown Royal).
