Toro tartar, and a whole lotta eggs.Following the lead of newcomers Izakaya Ten and Zenkichi, the once-formal Takayama has reinvented itself as Ariyoshi, an izakaya with a sushi bar boasting a lengthy menu of tempura, yakitori, noodles, and assorted plates like veal-liver sashimi. Though sake barrels and light boxes decorated with bamboo give the narrow, high-ceilinged space a serene vibe a world away from the noisy Japanese St. Marks dives (there’s also a small private room in the back), the prices are reasonable: $2 for two gelatinous hunks of beef tendon in a stock of octopus, egg, radish, and tofu (there are ten other varieties of oden stew, too), and $2 for a skewer of salted chicken hearts. The toro tartar, one of the priciest dishes at $13, is a tuna portion large enough to feed two, topped by a quail egg sitting in a nest of flying-fish eggs. They're not serving cod sperm yet, but the manager says he’s considering it. Daniel Maurer
