Here is a cute idea from CocoKelley:
Traditions of Something Old, New, Borrowed and Blue - Your Signature Drinks!
Something old: Ask your grandma what her favorite drink is!
*Something new: Whip up something new using your favorite mixers!
*Something borrowed: How about a drink your best friend had at her wedding!
*Something blue: Anything with Blue curacao or blueberries works great!
You can have the wait staff serve these on the same tray or just set up a menu at the bar.
