An unlockable bar for serving mixed drinks could be fun

My suggestion is to have a bar that patrons can sit at in addition to the tables, but when they sit at the bar there is a mini-game for mixing custom cocktails. It would rely on having the base drink in stock (wine, ale, etc), but customers could request additional ingredients like honey, fruit, alchemical ingredients, and possibly some items that are specifically added to the game for mixing like bitters.
