We usually go to Disney in June - the end of the copper river salmon season. They have it at Artist's Point and California Grill (may have it other places as well - these are just two we know). It is different from the King - more subtle, little less fishy. Definitely worth a try.
If you happen to live near a Wegman's grocery store, they sell - along with the cedar planks - so you also make it at home!! (I have)
