Kotto's bento box lunches are tasty and a good mix of tempura, vegetables, sushi, salad and meat - a great value lunch! Other menu items are tasty and presentation is nice. Their green tea is very tasty too!
Servers are kind enough to split the bill if asked, but food service can be a little spotty - sometimes everything comes at once, sometimes only some dishes come while others are delayed.
Overall: Kotto's a great place to go on King West, where sushi places tend to be few and far between, and the prices are reasonable.
