If you want to spend the money, then go to Victoria and Alberts.
However, if you cannot justify that much for one meal, or like us, can't afford it, I would recommend the Yachtsman Steakhouse. The service was definitely top notch. Refills, and anything else you need just seems to appear out of no where, as the servers are very unobtrusive, but always there when you need them. The food is beyond words. Nowhere have I ever had steaks like these. They melted in our mouths and I like mine medium well, if that tells you anything. The desserts were fantastic, as well. We went for our anniversary and before we left, they delivered a single red rose and placed it in front of me--- this was on a Tuesday and the rose opened and I was able to enjoy its beauty for 5 days--- pretty good for a rose.
