A lot of places have all their draft lines run to a single cooler where they store the kegs, whether CO2 or NO2.I went to a Christmas party last month at a rather nice establishment and I ordered a Guinness and the bartender sat it on the bar.... Now I only get to drink a beer these days about once or twice a year so I was pretty happy they had a dark beer, since a year before they had none. But back to this last time . I took a sip and it was COLD:cuss: I called him back and asked him why on earth he would take a perfectly good beer and ruin it by refrigerating it. He looked at me like I was crazy and walked away. Luckily we had a bit of a wait so it had time to warm up before I drank it. You will still find an awful lot of people in the US drinking their beer cold. But then I don't even drink cold water anymore so maybe it's me.
