I've been following the thread since I last posted. I've come to some conclusions of my own in which for the price of their burgers, they really aren't bad especially for the price.
For arguement's sake, let's just choose a deluxe wally burger with mushrooms and fried egg. That in itself is in the range of ~5-6$. After finishing the burger, I would be pretty satisfied and full. I would pass on the pop and fries altogether.
Some may argue that they're Costco patties. I beg to differ. I went to Costco several times throughout the week by chance and took a look at their frozen beef patties. They don't sell anything even remotely close to what they serve at Wally's. I believe SlySi is right in which their buns and beef patties are unique to the business. Never have I seen a burger with such intricate buns nor beef patties. Sure, we could make a better burger at home. I won't argue that but the amount of time and effort it takes to make a burger of such calibre and beyond is not worth it for some people. I remember when the Koreans were running the show and definitely the beef patties were from Costco. But not this time around.
Despite the fact that they may not be up to par to gourmet burger joints such as Vera's and Splitz, they seem to have a different appeal altogether by offering a simple, rather nostalgic burger to people of all ages. You don't need to be a Yaletown Yuppie to enjoy a Vera's nor do you have to be a Main Street Hipster to hit up Splitz. Wally's is just a burger joint where everyone of every age and stature can go to have a great burger which brings back memories.
