Here's one that no one's mentioned yet but I love eating there... the Costco snack bar.
Nowhere else can you buy a chocolate-dipped ice cream bar the size of your bible for only $1.50!
I love their chicken bakes and combo pizza too and now they have this sort of turkey melt sandwich which looks really good but I haven't tried it.
And of course their hot dogs and polish sausage are good too!
