I tend to not order cocktails at “normal” bars.  There are just too many variables if the bar doesn’t specialize in cocktails, in my experience.  When I do, I consider the Manhattan to be one of the most reliable drinks you can order at a bar.  Whiskey, sweet vermouth, bitters.  Not complicated.  And always delightful and you can call out a particular whiskey, if you don’t want to roll the dice on their well whiskey.  I typically make mine a Makers.
