Reader Marlowe says that Kai Sushi at 738 State Street has updated the hours posted on their window to indicate that they are now closed on Mondays, Tuesdays, Wednesdays, Thursdays, Fridays, Saturdays, and Sundays. Unless Lennon and McCartney were right about there being Eight Days a Week, I suspect Kai Sushi has closed or gone on vacation. Their website still shows normal business hours and Yelp says they’re open so I called Kai when they should have been full of customers and the phone just rang, with to humans or voicemail picking up.
