John,
Do you have a dedicated person manning the siphone bar or do you have the barista doing both espresso and siphone drinks? I have seen pics here and at coffeed but can you describ a bit on set up and operation. For example how close are you to hot water source and sink. And how do you hand wash the glass or they are durable enough for dish washer? Lastly, how durable is the beam heater unit and the halogen bulbs?
