This place was THE place to eat if you were one of the many cooped up office folks at Richmond and Spadina when it opened. While the traffic has died down a bit it is still one of the busiest places on the corner.
For service and quick eats, CJ's has it locked. The owner is incredibly sweet and willing to work as many deals as he can into the lunch hour rush. It might be something as small as rounding your meal down to the closest dollar or throwing in free yam tempura but it's always appreciated.
You might not want to stay in and eat because it's just so small inside but if you're doing take out you might wait all of five minutes from line up to cash out. The long cafeteria style counter has a cold, sushi combo and hot section (for noodles, bento-ish trays and spicy fried chicken nuggets that are addictive).
This place would have been a solid 4 stars if it they had better prices but I find I spend the same amount for lunch at CJ as I do at other places and while CJ's food is tasty, it isn't the same quality.
