I just want to say that I had an absolutely fantastic dinner last night at Next - dinner with close friends and thanks to a really wonderful staff, I felt as if I was dining at a good friend's home. To say that I have nothing negative to say about the service last night would be really unfair to Next . . . the staff was warm, friendly, and amazingly knowledgeable about every aspect of the restaurant. So much of the discussion here has focused on the food and concept, but let me tell you that the service takes the entire experience up several levels.
Let me first start by offering up some advice to those of you still trying to score a table. Pay close attention to Next's Facebook page. There seem to be fewer releases of tables these days (maybe only one large release per week), but in greater numbers of tables at one time. Tables seem to be released at 10:00 or 10:01am and when you see the white date click for your life and immediately select a table size and time. Don't waste precious breaths - there's no time for thought as the tables will be gone in an instant - or 3 seconds as the case may be.
But wait, there's more. Some people will have clicked furiously at 10:01, only to secure a table that they decide they don't want. In that case, the table will be released back into the system 10 minutes later, at 10:11am. Perhaps then again at 10:21am. Be ready to pounce. If you think it's crazy and don't have time for this, so be it. Demand will eventually settle . . . maybe for Bangkok 2060 or whatever comes next.
As for the food last night, we were a table of 4 and had everything already discussed, plus some extras. A couple of notes on items already discussed: 1) I don't know how they got butter to taste so good, but this butter is out of this world, and 2) the Bombe Ceylon was . . . the bomb. Personally, I just loved it and found it the perfect finish.
We were fortunate to have a few extra dishes last night (although not at a kitchen table). One, small gougeres filled with just a little mornay sauce - delicious. We were also served the lamb dish pictured in RonTam's post. It was wonderful - the lamb sweetbread was my favorite part of the dish, but it also featured lamb rillettes, lamb tongue and really fantastic onion rings (without listing every element of the dish).
Pre-bombe we were also served the sorbet sauternes - sauternes frozen with liquid nitrogen . . . some of it melted (intentionally) leading to a part frozen, part drinkable, sauternes. It was outstanding too. Here's a bad picture, but a picture nonetheless:
Sorbet SauternesDinner was followed by a tour of the kitchen. I was intrigued by the number of induction cooktops:

Lots of east coast sole waiting to be prepped:

A "Sole-less" ménage à trois of crawfish shells ponder their next move (sorry, but I don't pretend to take myself too seriously):

After at least 3 hours at Next, two of the four of us moved on to Aviary for cocktails (maybe at 12:15 or so) and were pleased that there were tables open. If you'd like to hit up Aviary, I suspect you'll be able to get in.
All in all, a terrific night . . . outstanding food, equally outstanding service, and although I could probably dissect the whole experience and find minor flaws, why bother. I never believed the dinner could live up to the expectations I had built up in my mind. Yet in fact, it exceeded my expectations. I can't wait to see how they interpret Thailand.
