We have a friend in town for the weekend and want to go out for Sushi. We have no car so it definitely has to be Cambridge or Boston. Our spending limits are about $50 to $60 per person (this includes tax, tip and drinks). I have wanted to try O Ya and Oishii but I am worried that we won't be able to have a decent sizes meal for what we can spend. So, the question is, where in Cambridge or Boston can we get good Sushi at a price point of about $50 per person?
