My wife and I ate at V&A last week for our 10th anniversary dinner. We had extras on the foie gras, the abalone and the Kobe Beef. I had the wine flight, and my wife had two glasses of wine. Our total bill, with tip, was approximately $450.00.
As for the food and service, neither my wife nor I would characterize either as "ordinary" or "disappointing." We have dined in Michelin-starred restaurants in France and in top restaurants throughout this country and in other countries, and agreed that both the food and service were comparable to the food and service at our favorite and most memorable meals. That said, it's a matter of taste, and your impressions could depend on what dishes you order that night (I tend to order some dishes that I know I will like, and some dishes that I want to try for the experience -- like the abalone). If you like simple seasonings, familiar food, or have a problem with creative combinations of ingredients (i.e., you look at the food prepared on "Iron Chef" and shudder with horror), this is probably not the place for you.
As for the creme brulee experience, it is disappointing that it wasn't replaced. Our own impression of our "Alberts" was that, if we had asked, the dessert would have been replaced with a smile and an apology. My own experience, especially in a place such as V&A, is that if I speak up and ask for a replacement (based on the faulty preparation of a dish), then it will be provided. I do not expect, however, if I leave a dish uneaten and do not complain about the way it was prepared, that the server will know that I had a problem with the dish. Good servers may seem to be mind-readers, but they are not.
BTW, I did comment on how one of the wine pairings did not work, but that was more of a discussion with the server about a failed but noble attempt of matching food and wine, instead of a complaint. The wine was fine, but didn't compliment the dish I had (abalone). My "Albert" told me that he would pass my comments on to the sommelier, but I did not expect a new glass of wine or something extra because I spoke up (it would have been different if the wine had turned bad).
