In the wasteland that is Keele & Steeles, Genji Sushi is a welcome oasis of good quality food. It's an especially great place to get away from the York campus for lunch. Good sushi, a bit pricier than some of the cheap downtown places, but this is a much more thoughtful product. Good lunch specials and really great decor!
The place gets crazy busy around noon so try to come a bit earlier to get a seat. It's a small place, and so they may not be able to accommodate parties of more than six at one table.
