I actually use both terms (dresser and chest of drawers... although when I was really little, I remember thinking the term was "Chester Drawers." Hee!) pretty interchangeably.

I think that "wardrobe" doesn't get used as much in the US, mostly because most houses have built in closets, so it just never really made it as strongly into our vocabulary.

As for the place where you keep food? We have a pantry, but we also keep food in what I would call the cupboards.
