He messed it up. The hashbrown has an indented "pool" for the gravy, which you can see in my picture. But he's right about the mayo - in fact the "pool" was filled to the brim with it, so I had to scoop it out in order to fill it in with the gravy.Those things seem like Lay's Potato Chips where they are so good you can't eat just one. How many did you have?
I see Canadians like them, kinda-sorta...
I just had one. As he mentioned, they are expensive. Just by themselves they are already more expensive than any other fast food combo. 2 McValue meals would be cheaper and more filling. But probably worth trying once.
