Liz recounts a sorry lunch  at Osushi in Copley Place:
This place is only surviving on Groupon deals and unaware conference attendees. Don’t go to Osushi (it's difficult to find in the mall, so maybe if you tried to go, you gave up and went somewhere else, anyway). There are plenty of less expensive sushi places in Boston that have fresh fish and good service.
