OH, YEAH

O Ya's nuanced sushi-fusion dishes like foie gras nigiri with balsamic-chocolate kabayaki sauce and raisin-cocoa pulp will delight and amaze adventurous diners not afraid of a big bill. (While you're spending big, go ahead and try that dish with the eight-year- old sake.) Nothing about O Ya, in the Leather District, is expected, but conversation-stopping menu items, cool decor, and gracious hospitality all contribute to a transformative food experience. O Ya, 9 East Street, Boston, 617-654-9900
