Good one! I like how all the drinks are half-finished, gives the puzzle a nice tidiness.
I guessed the mechanism right away, but I needed Google to figure out half the drinks. Bra was especially tricky lol. Highball I had no idea, I tried High Tea for a while.
I'm glad Will asterisked the clues because US Mint would probably mess with a whole lot of solvers (Mint Tea? Mint Julep?)
