Given the tariff for the room, the menu choices/quality at the restaurant and bar/wine stock was alarmingly dismal (e.g., the wine list would be an unmitigated embarrassment to even a mediocre bistro in Coral Gables, Florida, even though at this property you are in France!)l!!!! (But, still the view almost made up for these deficiencies.) Now that I have been there and once had the view going to sleep and awakening, I would never, ever pay this tariff to go back given this property's other defieciencies!! (Though, admittedly, nothing nearby appeared to be better and none had the view, but at least one I stopped at had a FAR superior wine list.) In sum, not a luxury hotel justifying the price. It is all about the view (assuming no fog/rain) and convenience.
The views from the room, restaurant and patio are fantastic, stupendous, awesome, incredible -- cannot be beaten!!!!!!!! The ultimate "room with a view"!!!!!!!!!! And, it is as convenient to Mont Saint-Michel itself as one can get without booking a hotel on the Mont itself (or sneaking in by landing craft). If this is what all you want and you do not mind the hefty price, do it! and, if it is your honeymoon night (or some equivalent) you are planning for and can afford it, ABSOLUTELY DO IT!!!
