We're really looking to do a signature drink at the bar. It's open bar but we want to steer guests towards a cocktail that goes with our theme. We are doing tropical but trying to do it in an understated, more classy way. We would love a tropical drink to feature as well as a pretty flower garnish on it. The problem is there are so many kinds of drinks its hard to narrow it down and search for them plus find something yummy. Any ideas?
