My fiance is a bar manager and loves creating new cocktails. His idea for favors was to make some signature cocktails and bottle them for each individual guest. The idea is to make two different types of drinks. Is this something people would like to receive? Would an "airplane" size bottle be okay if each guest got two (one of each cocktail) or should we go with a bigger size? We will be having an open bar at the wedding so this will not be the only alcohol provided, but actually a gift for our guests. Thank you for any advice!
