One place you absolutely have to go to when in Juneau is the Red Dog Saloon! Can't miss it as it's only about 2 blocks from the pier on the main street. I love places like this! Even if you don't drink, you have to see the inside.
And speaking of saloons, if you're going to Skagway, another favorite one I like to visit is the Red Onion Saloon. As they advertise, "Since 1898 Skagway's most exclusive brothel!"
