I recommend linking to state statutes and sections of "Alaska Administration code" as there are shady areas which are not explored. Alaska is a young state, thus there is not enough case law to say "XXXX code is not valid", like the AAC (Alaska Administration code) restricting firearms at the Anchorage and Fairbanks international airports.
In regards to Alaska state statutes, they're listed online. There are no prohibited places specifically to open carry. The places which firearms are restricted cover all methods of carry.
If you do place open carry as "OK" for places which serve alcohol, which include Red Lobsters, Applebeed, etc. Make sure to mention there are no court cases to back it up in any of the courts I've searched. The statute specifies carrying a loaded firearm is prohibited in places which serve alcohol.
There is nothing stating the carry of an unloaded firearm. I should note there are court cases in Alaska which do state where criminal behavior has ensured even though a weapon is unloaded, if the person purposely gives the intention of a firearm is loaded then the weapon is loaded in view of the legal system.
State statutes and case laws are my bed time stories, I read case law instead of novels since they're so entertaining.
