NY Palace Towers
It will be interesting to see if Dorchester improve the service and, most especially, the room service in the towers, as when I stayed in one of their suites, room service and food quality were Marriott level, as the food came from the same kitchens as the main hotel. Despite having a large dining room in our suite, the 'butler' wheeled in a tacky trolley with a pink cloth and cheap tablewear and glasses and then proceeded to set up this makeshift table in the sitting room.
The Lowell, on the other hand, is what I call real high-end - immaculate service throughout.
