Not as wide spread but Burger Queen is better than Burger King IMO

...based on my experience when I stopped by Ketchikan years ago:

Burger Queen in Ketchikan, Alaska
Burger Queen in Ketchikan is frequently cited by locals and travelers as having the best burgers in Alaska. This family-owned institution has been operating in the same location since the 1980s, serving charcoal-broiled burgers and old-school milkshakes in a no-frills setting. It's often frequented by cruise ship crews and locals. Known for its high-quality, made-to-order burgers, it is a staple for a quick, classic meal, with many locals calling in orders ahead of time
