I think it would depend on the style of dresser. I have a smallish one in my dining room that works quite well as a small buffet/sideboard. It has 2 full width drawers and 2 half width plus is raised on legs about 16 inches tall so I don't think it is obviously a dresser.
Of course, with the popularity of armoire style cabinets used as entertainment centers and other main room uses, using a dresser in a new way doesn't seem all that odd.
