Robots.
I honestly thought the Tipsy Robot was awesome. Yes, the drinks are about 10$, but that includes tips and the honestly the entire experience.
You get to use touch pads to choose your drink. Once you choose what you want it sends you a text with your receipt and how long it will take to make your drink. I really love places like this that incorporate technology.
I mean don't expect an humanoid AI robot, we are not completely there yet. Maybe one day. For now this is awesome. You will always get a consistent drink here.
