Just got back from Shanghai and I can report on Jean-Georges (3 on the Bund).
Food: I had the full chef's tasting menu, with wine pairings (we'll get to that later). It was delicious, though rather conservative. The amuse bouche was the most radical part-- while most amuses are light and cleansing, this one centered your palate by way of the extremes. Notable dishes were the frog legs with a salty-tasting broth (I am a sucker for the injection of local flavors into menus like these); and the monkfish.
Service: Impeccable. As to be expected from a top-tier restaurant, it was attentive and timely, but with a genuineness that reminds me more of Europe than NYC.
Wine: Disappointing. I came to China braced for a wine nightmare, and that's basically what I got. The wine pairings were selected on-the-fly by an assistant manager, since the sommelier quit a couple of months ago (how can a place with Vongerichten's name take so long to replace a sommelier?). The wines were mostly Australian and Californian, although I specifically requested an emphasis on Bordeaux and Rhone. They were hollow, fruity, and cheap. As I tasted each one with the meal, I easily listed 3-4 French wines in my head that would have gone better with the dish and which retail for $30 or less.
Atmosphere: Mixed. There is no dress code whatsoever, and I think this is a bad thing. Touristic families came in with children wearing athletic wear and flip-flops. Remove all the people and the dining room has the ambiance of a classic French 3-star restaurant, while the bar/lounge area looks more like a NYC lounge (e.g., The Modern) with slightly thicker cushions. Add the people, and it feels more like Las Vegas (especially with the bright lights of the Pudong skyline pushing through the welder-tinted windows)-- classy couples, loud families, quartets of businessmen, and slimy porn producers all scattered around the place.
On my next visit, I will try Laris, in the same building a couple of floors up. The menu looked spectacular and the atmosphere and service at least as good as J-G's.
