Ken Oringer's intimate 40-seat izakaya offers Boston's finest Japanese-inspired cuisine. The omakase sashimi, uni preparations, and Japanese whisky selection attract serious food lovers from across New England.
Uni at 370A Commonwealth Avenue in Boston's Back Bay is chef Ken Oringer's intimate 40-seat izakaya, widely regarded as one of the finest Japanese-inspired restaurants in New England. Operating in a below-street-level space within the Eliot Hotel, Uni channels the focused energy of Tokyo's best izakayas — counter seating, an open kitchen, an exceptional selection of Japanese whisky and sake — while drawing on the full range of Oringer's culinary training to produce a menu that goes beyond traditional Japanese restaurant conventions. The omakase sashimi program, in which the kitchen selects and slices daily seafood arrivals based on peak quality, is the centerpiece of the menu and a showcase for sourcing relationships with Japanese fish markets and New England fishing boats simultaneously. The sea urchin preparations — both domestic and imported varieties of the crustacean from which the restaurant takes its name — are presented in multiple preparations that demonstrate the range of ways this complex ingredient can be treated. Japanese whisky receives the same level of curatorial care as the food, with a selection spanning Japanese distilleries and aged expressions that are rare or unavailable elsewhere in Massachusetts. The dining room's compressed size — 40 seats total, many at the bar counter — creates an intensity and intimacy that distinguishes Uni from larger, louder Japanese restaurants in Boston. Reservations are essential and fill quickly.

Frequently asked questions
What is 'uni' and why is the restaurant named after it?
Uni is the Japanese culinary term for sea urchin gonads — the intensely flavored, briny, and creamy part of the urchin consumed as sashimi or in cooked preparations. The restaurant is named for this ingredient because it represents the Japanese culinary philosophy of focused, high-quality seasonal ingredients.
Is Uni a traditional Japanese restaurant?
Uni is a Japanese-inspired izakaya that draws on Japanese culinary philosophy, techniques, and ingredients but is not strictly traditional. Chef Oringer applies broader culinary training to the format, resulting in creative dishes that sit alongside traditional Japanese preparations.
How many seats does Uni have?
Uni has approximately 40 seats, including counter seats at the bar and small tables in the dining area. The intimate size is intentional and contributes to the focused atmosphere.
Is the Japanese whisky selection extensive?
Yes. Uni maintains one of Boston's largest dedicated Japanese whisky collections, with expressions from multiple distilleries spanning standard releases and aged rarities. The bar team can guide visitors unfamiliar with Japanese whisky styles.
