cute little kegs, all i use at work and party's are the 50L ones.
i have a actuall cold plate and beer gas hookups. so i just pour it like at a bar. no pumping and such.
you just take a ice cooler and drill some holes in it and run your beer tap off it. have oyur beer lines run through a cold plate that sits under the ice in the cooler.
some of the stuff i have gathered from managing a pub for so many years.
LOL
what were ya using for the beer? guinness and what?
