I think that the main dining room is much more romantic than the Chef's table - dim lighting, harp music, etc.
We are spoiled by the Chef's table though- We usually go with friends, and love laughing and interacting with the Chefs--- Plus we are Foodies, and the sounds and smells of food being prepared is "romantic" to us in it's own way! But you do give up candlelight and music- and when you go to the restroom, you have to walk thru the waiter's prep room (not very romantic) on kitchen tile floors and thru the restaurant to get there (It's a 3 hour plus dinner). One more thing- on our last visit, the manager brought back 2 couples (at 2 different times) who were dining in the main dining room to take a peek at the Chef's Table ((I guess they had inquired about it))- sort of made me feel like we were on display (That was the only time that has happened and we've dined at the Chef's table 4 times)
I think it all depends on the atmosphere that you are looking for! If you want the chef's table, be sure to be on the phone at 0700 exactly 180 days out in order to book it!
