Osushi’s single dining room, with its frenetic street views and minimalist black and red decor, attracts Copley Westin tourists and sushi-loving movers and shakers. High-backed booths are perfect for couples looking to loosen up via the sake train (there’s an excellent list, including a delicate, pear-infused variety). Harried hotel guests and solo diners can saddle up to the tiny sushi bar, where expert sushi masters dice and roll the night away.
