Can they fill growlers at places like this in ND and if so what kind of prices do they charge and will they fill misc. growlers (I have perhaps 20 or so)
Yes, they fill growlers. I don't remember pricing on growlers, nor do I remember if you can fill other growlers. sweetwillyrolbar would be the person to contact for more info.
Price range depends on the beer, usually $15 on the low end (i.e. seasonal Summits) to $20 or so on the high (i.e. Southern Tier 2x Stout), but not everything on tap is available for growler fills. I just picked up a growler of Fargo Brewing's porter - the sample was pretty good. I've never tried to fill other growlers.
