For me at least, $50/person restaurants are in the "nice" category, but not necessarily in the "really fancy" category. If you're ever in New York City, I would heartily recommend the restaurant Acquavit (restaurant review here (http://www.newyorkmetro.com/pages/details/2270.htm)). Marcus Samuelsson is a really imaginative chef, and I strongly recommend the $125/person mutltiple (usually 15+) course tasting menu. The flavors are truly amazing, and the presentation of each bite-sized tidbit is always imaginative. Good stuff, but including wine, it's easily $150/person. And of course, with the waterfall located in a multi-story high dining room lined with black marble inside a skyscraper in midtown Manhatten, it has a very nice ambiance as well. A good place for fancy anniversary celebration (at least if your partner is into such things).
