Double Musky makes a decent version of Cajun cooking....there are some places in and around Ewe-stun, and particularly a couple hundred miles to the East that do it better....but I've never been a fan of the ambience at Double Musky and (for me) its a distraction from the food.
That being said, the Double Musky Pepper Steak is about the best pepper steak in Anchorage (that I can think of) and (whether pepper, Bearnaise, truffle, mushroom, or otherwise) Double Musky offers uniformly excellent sauced foods; without a doubt, Double Musky offers the best cajun food in the Anchorage area, although I think they would style themselves as more creole than cajun.
Since Girdwood is almost exactly 45 minutes door-to-door from my Anchorage house, meaning Girdwood, not just the turn-off, Double Musky, Seven Glaciers, Chair 5, or even the Sitzmark are often worth the drive, particularly (for Seven Glaciers) near the end of their season when the tourist crowds have died down a bit.
