Review by David Welbourn (originally posted at Baf's Guide)
'Fresh Sushi' is a treat. It's not a challenging or long game: all you need do is feed your friend's pet fish. But it shines in its treatment of its characters. This is most notable with the pet fish, who has a boorish comment or reaction for almost everything you do (including new comments on repeated actions, in some cases). But it's also clear that some thought was put into both the player character's character and also that of your absent friend, whose art studio you are visiting (eg: look at the painting).
