When we went there for the first time in Sept. 2005 it was amazing! We ate kind of late (after 8h), and the restaurant was crowded but not packed.
We went back in Oct.2006 and we were really disapointed... the food, although good, was not as amazing as we remembered, and it was actually lukewarm (a big nono in my book). It was also way too crowded, and we were there around 7h30.
Not a bad restaurant, and if you really want to try it I would say you should go for it, but may be avoid peak dining hours...
