Ten-Ichi is one of the best all you can eat japanese restaurant I've been to in Toronto.
Food is consistantly good, servers were friendly and attentive, and most importantly the food selection is very good (they offer all the basics covered and more such as house specialties)
It's popular dining spot during the middle of the week which says a lot, so definitely call the 'hotline' to make a reservation to avoid disappointment.
Only thing I would say the restaurant needs renovation; things are a little worn down. Tables, chairs, walls, decors. Still a fan though.
