Sushi by Bosso Ramen Tavern

Sushi by Bosso is the Newbury Street member of the Bosso family, separate from the ramen tavern in Harvard Square. Sushi is a particular draw here, and Sundays bring an all-you-can-eat service with nigiri, rolls, sides and dessert. Choices include tuna, salmon, yellowtail and tamago, along with salmon rolls and spicy tuna rolls. Premium additions such as uni and eel cost extra.

The Sunday service runs from 1 to 6 p.m., with the last seating at 5 p.m. That’s a specific weekly offering, so don’t assume an ordinary weekday reservation includes unlimited sushi. The restaurant also publishes separate lunch and dinner menus and takes reservations through Resy. For a group that wants to spend an afternoon working through different sushi choices, the Sunday format gives you a clear plan.
