Four Seasons Hotels has set the bar for many things in service but now they are promising that room service will be delivered within 15 minutes! (by the end of the year according to this article) Some resorts will have a 20 minute time limit owing to distance etc. But given the menu items at these places, any short term limit is more than amazing.
We'll see on Flyer Talk if the takers of this deal are satisfied with the fare and the speed. When I attended culinary school (taught by the chef of Club XIX btw) he commented that most if not all dishes could be finished in less than 20 minutes assuming a good deal of prep and garde manger. It remains to be seen if the customers paying these rate agree.
