Best of Boston

An epic tasting menu, when properly executed, should leave you enthralled and satisfied, not stumbling out of the restaurant in a food coma. O Ya understands this, which is why its 17-course omakase strikes a tantalizing balance between indulgent, rich dishes (squares of fat-marbled Wagyu steak; custardy chawan mushi dotted with trout roe and Santa Barbara uni) and more-delicate plates (hamachi with spicy banana-pepper mousse; mushroom sashimi with ethereal sesame foam).
