This is a very tough question to answer. My DW and I put off going because of the expense for a long time. When we were in a position where we felt we could afford it without too much hardship, we went. It was incredibly fabulous, and worth every penny. I have just a few comments:
First, go only if you're relaxed about spending the money. As others have said, if you are stressed about the cost, you won't enjoy it.
Next, if you are "meat and potatoes" folks, or if you are not food adventurers (like to try different and varied things), or if you like to get in and get out of a restaurant, and do not like to linger over a meal, then consider not going. Any of these preferences or similar will spoil it for you. I'm not passing judgement - some people just will not enjoy V&As because of their personal preferences.
The staff will make you feel really welcome and relaxed, and will pamper you and take care of your every need. The service is impeccable and absolutely unexcelled. If you can relax and really not think about the money during your visit, and "put it aside", and if you are not uncomfortable being treated like royalty (really!), then go.
The food selections will be "different" and intersting. The presentation will be awesome. The waitstaff to client ratio is about 1 to 1, so you will not want for anything. At one point I pushed my chair back a little, and our "Victoria" was there to help me and ask if I needed something. When I asked where the rest rooms were, she escorted me there and showed me. When I returned she was there to push in my chair and hand me my napkin. It's that kind of service. But at no time did I feel out of place - they always made us feel ultra relaxed and comfortable.
If you are the type that really appreciates that kind of fine service, then this place is for you. If not, it might not be worth it. It's really a matter of personal choice.
If you are a picky eater - not to worry. Someone will call you the day before to discuss the menu with you and find out if there are any special needs you have, or if you dislike certain foods.
Expect to spend 2-3 hours dining. I don't remember the dress code exactly, but you can call and find out. Jackets for men and suits or dresses for ladies - something like that.
Good luck, and whatever you decide, I hope you have a magical trip. And congratulations on your marriage!
