To the best of our knowledge(And i have been known to be wrong before!) , Long Pants are
REQUIRED only at the "White Restaurant" (Il Piacere) and at Suki (The japanese). The buffet is more casual.
As for the sandals, I suppose that depends on the actual pair, but I will offer this advice...... make sure that whatever you wear is complimentary to the outfit that your wife/girlfriend may be wearing. We noticed last time we were there that many men didnt look like like they "belonged" with there S.O.
In short, if our ladies are putting in the effort to look AMAZING (and they usually do!) the least we, as guys, can do is make sure we "step it up" a notch, so they are not actually embarrased to be seen with us. LOL
