Japanese: A shoji-screened window and a small sign are the only indications that this nondescript brick building houses some of the finest sashimi in Boston. Chef and owner Tim Cushman works with his chefs to fuse exotic flavors with the purity of small morsels of raw fish. Expect small plates like wild bluefin chutoro tartare served with a homemade ginger kimchee jus and wild spot prawn with garlic butter, white soy and preserved yuzu. Of course, there's a price to pay for these bold and delightful bites - each plate starts around $20, and you'll need several to constitute a meal.
Sushi: Locating this nondescript building is just part of the fun of dining at Boston's most expensive sushi restaurant. O-Ya's tiny sign is easy to overlook on the brick building it calls home. However, once found O-Ya is an amazing experience in exotic flavors that are fused into the sushi it serves. Small plates dominate the menu and start around $20, a sampling of several are needed to complete a meal, but the sushi you'll devour will more than make up for the money you'll spend here. Enjoy the wildly different selection of raw fish like the Suzuki Sea Bass served with a cucumber vinaigrette, avocado, and cilantro or the Salmon Tartare with a cucumber yogurt coulis, argon oil and dill-simply divine!
