I received a Private Message today with the following question:
"Hey there - we are headed to Juneau in a couple of weeks with our 20 yr old niece - do you have to be 21 to go to the Red Dog?"
It's such a common question here I figured it would be helpful to more folks if I posted my answer out here in the open rather than being greedy and keeping things in PM land! ;-)
Alaska State liquor laws allow a minor to enter an alcohol licensed premise if they're accompanied by their parents or legal guardian. Most bars have specific house policies relating to how minors are supervised, where they can (or not) sit, etc.
Hundreds of minors enter the Red Dog Saloon every day in the summertime, so I would imagine you and your niece are in for a good time.
Happy Alaska Travels!
