I agree with you, am pretty anal about my garnishes, pimento facing up, etc. I
also like my garnishes to add something to the drink, as well to be a
conversation piece. Does this mean that you get a fruit salad with a cocktail
hidden somewhere in there? no. But first thing's first it should be visually
pleasing, having contrasting colors, red garnishes for green drinks, and so
on. Secondly I think they should compliment the drink in flavor. That doesn't
mean be a slice of the main flavoring agent in the drink. Just my opinion that
variety is the slice of life, and life ain't a slice of lemon. (unless you
need that last piece of lemon to finish the drink, in which case carry on.)
