Champagne is a bait-and-switch; be warned. The included champagne comes with the desert. If you order at the beginning, they will charge you €11 each and bring you 2 more glasses at the end. At that point, you have to chose between being the ugly American and make a stink, or just pay and deal with it.
Other than that, the views were great, ride was very smooth and the food was better than I expected. Chicken was good - moist and good flavor.
