LIke others have mentioned, you won't get the same character as from a Belgian yeast. However, I disagree that it will be drier. The Champagne yeast cannot metabolize any more sugars than most other yeast strains can (in fact, I'm pretty sure lager yeast can metabolize more). Champagne (and other wines) are drier than beers because they have more fermentable sugars, not because of the yeast. Champagne yeast is a great yeast because it can tolerate high alcohol levels, low pH, and low nutrient levels (conditions that other yeast have difficulty with), but it will not dry out your beer (unless you are comparing it to a low-attenuating British strain).
