I have a hobby project that's an automated bar called Booze Chimp. The prototype works great, but I never got around to updating the web site - the pictures are still from the really early project stages.
It has an industrial touch screen display with a really slick interface. You tell it your ingredients and it builds a database of all the drinks that it knows how to make - filterable and sortable by popularity and ingredients. It can also do things like make a one shot "Peach Long Island Ice Tea" that has six ingredients. Did I mention that it's portable and runs on a wheelchair battery?
Unfortunately, we couldn't end up justifying PLC control. The PC had to be there anyway. It runs a Java application that controls the pump and valves via USB relay boards. Not exactly mission critical for it to run a 365 day 24x7 operation.
I was working on the exact same project when I was a bartender. Never got further than the sketching though.
