Bouloud, or Kings Carriage House>
We have not been to King's Carriage House, but as has been pointed out, it is not in any way, shape, or form in the same league as Café Boulud. As gutsofsteel said, Café Boulud's dining room decor was recently refreshed, and they have now added a very attractive and comfortable bar room down the hall, Bar Pleiades.
Since you have been there before, you might recall that Café Boulud offers 4 different a la carte menus. They are provided on the restaurant's website, and you can scroll through them. (Far better than using MenuPages where menus are too often *not* up-to-date.)
