From the introduction:
The adventure begins in a popular tavern that has a very unique attraction: the staff are all automated constructs. You can simply say what you want out loud at any time and your order is prepared and brought to you automatically. Plus the prices are cheaper than usual and the food all tastes great.
If the players order any food or drink then a flying quill will acknowledge their order and fly to the kitchen. A golem waiter will bring them their order, and a flying coin purse will take the money from their pouch, hold it up for them, and ask to take the money as payment. If they confirm then the money is taken and food is given.
They've come to this tavern to meet with a potential contract who requested that you meet at this tavern specifically.
