Nolbu has a pretty extensive menu, great deals (like cheap oysters on Thursdays) and a nice lunch special where they don't downsize the sushi rolls. The customer service style is laid-back and so just relax and enjoy. The sushi is always fresh and the appetizers are great. I like their miso soup here, too and great choices for sashimi. I order here like twice a week and always try new items. You will always see the regulars--this is a gem in the Yonge/Sheppard neighbourhood!
Oh, and the prices are very fair especially considering the generous portions you get!
They are also very child-friendly and catered to me quicker with a little baby. (They have high chairs as well!).
