The update seems more definitive than before. I would think they would try to enforce it. There may be some factors in play as to why they changed it that we don't know about. I've noticed the dining rooms being less utilized over the last several years, that could be a reason. Who knows?
No offense anyone, but I will not be wearing jeans to the dining room. Just a personal choice regarding what I think is appropriate for that level of service. Besides, all of mine fit tight and the chocolate melting cake might result in their breaking point.
I don't have a problem with anyone else wearing nice jeans. Again, I like the dress shorts option for the non elegant nights. I just hope the Maitre'D doesn't interpret that as old long cargo shorts hanging..well you get the picture.
