I have been going to Ginza for years now. Initially we started going there because of it's close proximity to my parents' place, but we keep going back because the food never disappoints!
The restaurant is clean and well maintained (they renovated it about a year ago and it looks great!). The staff are also very friendly and informative.
I often go and order food for takeout, but they are still very hospitable. They always offer us a table and serve us green tea while we wait for our order to be ready.
They have several innovative types of sushi rolls that will ensure you'll never tire of the selection. The fish is always fresh and delicious! I especially love their miso soup in comparison to other sushi restaurants. It's not overly salty and has lots of tofu and seaweed.
I also appreciate that their edamame is reasonably priced. I've been outraged that other establishments are charging upwards of $4 for edamame. Ginza's is only $2.95 and they give you quite a fair bit.
This location is my favourite, but I've been to the one on Bay a few times as well. It's good, but doesn't have the same feel as well as the North York one.
