They are two completely different restaurants. If you have spent some time looking long and hard at all your other options and these are your top two, then timing may well make the decision for you.
Le Cellier books up really quickly - often within hours of the 180 day mark. This is not to say that cancellations don't happen - they do -but you may need to be a lot more persistent to get a reservation there. Nine Dragons on the other hand would be comparitively easy to snag a reservation.
Le Cellier is incredibly poplular. Nine Dragons gets mixed reviews. Now coming from someone who often does not go with the majority, I would say if you are leaning toward one or the other, give it your best shot and don't be deterred by others' opinions. Go onto
www.allear.net and read some reviews. You can also check out the menus there if you have not already done so. Personally, I have never eaten at Le Cellier, nor ever even attempted to get a reservation there mostly because the menu doesn't really appeal to me, but also partly because I am slightly put off by all the hype (told you I don't go with the crowd

). Having said that, if I wanted a special meal as a couple and had to pick between the two, I would go with Le Cellier if there was availability.
Very difficult to tell a stranger what they would prefer, but hope that helps a bit. I am sure you will get quite a good response to this question with some folk being very, er .... enthusiastic about their recommendations and/or criticisms.
Whatever you decide, I hope it is absolutely magical for you both!
