I've seen the Bunn's in restaurants. They're quite common. I've never
really had a decent cup of coffee from them. One of the best commercial
cups  of coffee I used to be able to get downtown was sold by the CHinese
Dim Sum places. They had these big old glass pots with a drip mechanism on
top and something else, maybe a plunger? Not sure. Anyhow, they sold the
coffee with half-and-half (or light cream) and it was strong and good. The
Vietnamese place down the street makes it with condensed milk and half and
half. Strong and sweet. Good but too sweet for my taste.

That's a percolator.
