This place is extremely busy during office lunch hour. They're fast, convenient and tastes pretty fresh.
Then again, I wouldn't frequent CJs if I didn't work in the area. A common complaint is that their sushi rolls fall apart very easily and that the complimentary miso soup is too bland.
The spicy tuna rolls are covered in hot mayo and you can request extra on the side. The lunch box prices vary from $8 to $10+ so for those who are always like me, would be spending almost $20 for 2-3 lunch boxes. I suggest that they make a lunch box that contains more than 8 rolls.
The front patio has a great view of people bustling about on Spadina and is mostly packed during a warm day.
Overall CJs is A-OK. They could certainly improve in quality and more variety though.
