Kobo is the best sushi in Durham and possibly one of the best in the GTA. It is the opposite of cheap all-you-can-eat places. You pay more, get less, but it's memorable.
The quality of the dishes sushi and the flavours are clearly a notch above anything else. I believe it is Japanese run, which makes a difference -most sushi restaurants are not.
Omakase is the "chef's choice" and is recommended. They will provide the a mix of sushi of high quality and variety.
The tempura is flavourful and lightly battered, never heavy.
Decor is minimal and outdated, verging on retro.
The service is cold and to the point, like the sushi.
Watch the opening hours, they like to close early and don't arrive for dinner past 8:30PM it may not work so well.
