The best way to serve an Old Pal is chilled, but not diluted. It should be stirred with ice and then strained into a cold cocktail glass. Garnishing is not traditional for an Old Pal, aiming to maintain its clean, crisp profile. However, you might consider a lemon twist or a thin orange peel for a subtle addition of citrus aroma. Serving it in a cocktail glass enhances its elegance and allows the drinker to enjoy its complex flavors fully.
