We’ll get straight to the point: Tzarevna serves fantastic, fast-casual Russian and Georgian food. And this marks them out as being one of New York’s most original restaurants. But this isn’t deep-fried, unhealthy fast-food. This is authentic home-cooked fare from the motherland, cooked quickly. So expect real beef stroganoff, Siberian dumplings (these are so good…), and some of the best khachapuris in New York.
