on the subject of chicken instead of burgers... when I was in Tulsa, I was introduced to Charlie's Chicken... their chicken chunks (while not an appealing name) are far and above any other chicken I've gotten at a restaurant.
certainly if someone has a memory they're trying to get back to, it will trump the actual quality of the food... closest thing I have to that is Korn fritters from Sourdough Mining Co in Anchorage (Now out of business, but I have the recipe from when I worked there)
