wonderful notion, this....
(+ a few recent ones of mine...)
park hyatt dc - 5 deerpoints. blue duck tavern is really very fine (cherry blossom sorbet, astonishing apple pie, obamas + secret service, one michelin-star if michelin did a dc guide), but breakfast service brings it down considerable.
park hyatt paris - 6 deerpoints. michelin-starred restaurant (though trying too, too hard to please the inspectors), and very good breakfasts (kougin amann, proper parisian hot chocolate).
claridges, london - 4 deerpoints. ramsay's restaurant started off well, but went downhill fast. lately lost its michelin star.
umaid bhawan palace - 6 deerpoints. (though getting local spicing is sometimes a challenge... 'like the chef's mother would make it' usually does the trick.)
mandarin oriental london looks very promising, from recent buzz - heston blumenthal's place + bar boulud getting excellent notices. + after reading gallivanters' rave on the food (which put it at two-star michelin quality in the main restaurant), i'm also looking forward to grand hyatt berlin in november.
