I debated making a "bartender guide" but decided to let the dialogue loosely guide the drinks. IE they let you know at least one ingredient.... Most of the time... That you got wrong. They will say something like "I've never had X with Y" or "if it has ___, it would be perfect"
Then once you get the drink correct, it adds it to memory and highlights the ingredients anytime it's ordered in the future.
You also don't have to get anything correct unless you want tips. You can serve them ice... Or just poison.
