The Best Sushi On Long Island? Restaurant Yamaguchi in Port Washington -
If you live in or ever visit Port Washington and drive down Main Street, there is one thing you will notice immediately - there are a LOT of sushi joints in this little town. Most are good, but Restaurant Yamaguchi is spectacular, and trust me, I have eaten a lot of sushi in my life. Not Jeremy Piven levels, but close. It's no wonder this gem got a 25 in Zagat in 2012-2013.
