Neither...While our meals at both places have not been "bad," they've not been anything special either. In my opinion (and I'm sure some other folks will soon post differently) there are too many other excellent restaurants to waste dining credits at either of these places.
I am one of those few people that like Alfredos but between it and Chefs, I will pick Chefs de France. We have eaten there about 6 times and never had a bad meal
