We prefer Rose and Crown even though we enjoy French food more than English food as a general rule. Les Chefs is so crowded and the food is just OK, at Rose and Crown you can sit on the patio if it's nice and the tables aren't nearly so jammed together inside and we enjoy the food there quite a bit.
We've done Les Chefs twice (once as the Candlelight Processional Dinner package) and been disappointed both times; whereas we try to eat at Rose and Crown every other trip or so.
