I had forgotten about Petrossian, one of the better restaurants in Manhattan. They do have fabulous food, and your post caused me to look up their menu ... caviar & steak tartare as an appetizer for a very reasonable USD 22! And Petrossian uses Kobe beef (albeit from Oregon -- but it is excellent stuff, in some ways better than the original). The caviar is probably US farm raised (so ecologically sound). A class act.
