I freaking love this place. Great selection and great prices. You can go in with your regular Costco membership. When buying food in bulk it's nice to get the same stuff restaurants use! Their drink selection is fantastic and if you're into candy... You might want to steer clear because you're likely to want to drop your life savings! So much candy it's almost obscene.
I buy my low moisture whole milk mozzarella here, as it's a good price and most other places only carry low moisture part skim (why?!).
