For Anchorage, definitely hit up 49th State Brewing. It's super kid-friendly, has awesome views, and the food is great. Glacier Brewhouse is another awesome spot for seafood. When you're up in Fairbanks, check out The Pump House or The Turtle Club for prime rib.
Also, if you're taking
Alaska Airlines between the two or flying back out, the flights are super quick and easy. Have the best trip with your family!
