Pimm’s Cups are special to my fiancé and I but we’re trying to figure out if we can make it work as a signature cocktail given all the garnishes! I think if we pare it down to just a cucumber slice or mint sprig that it’ll be doable.
We had signature cocktails that were classic speakeasy drinks. I bartended years ago, and as long as you have a decent amount of garnish prepped, they don't add more than a few seconds to the make time. People also tend to drink more wine and beer at weddings, in my experience.
