I have been dreading this a bit (and putting it off), but the time's come where revising my review feels unavoidable. Things at Kushi Garden have gone down a bit in the last short while.
The menu has been revised (or more bluntly, reduced) for 2015, to just three items...curry, taco-rice, and a daily special. The daily specials in particular seem a bit more "basic" and bland now, with less creativity than before. The dessert choices have been severely scaled down as well, with generally just one, sometimes two items available. Fortunately, they do still have their great takeout sweets and cookies, and prices in general have stayed pretty much the same. Business hours are also (unfortunately?) unchanged...just lunch on weekdays.
One other thing I've noticed is a fair bit of staff rotation, which is probably related to all this.
And just to mention, Kushi Garden isn't particularly language-friendly for foreigners. The menu, blackboard, etc. are Japanese-only, and I have generally not noticed English speakers in the staff.
It pains me greatly to revise this review since I find this an example of the difficulties I've seen at vegan restaurants across Japan trying to succeed, and Kushi Garden in particular was so wonderful that this is extra difficult. In any case, the food is still good, and definitely recommendable, but just not as exceptional as before, and harder to recommend going out of your way for. One painful star less.
P.S. For fans of taco-rice, just note that there's no actual taco in the version here. Maybe a bit odd but it was still delicious so it never bothered me that much personally, but a friend was annoyed by this, so I just thought I'd point it out.
