I find Sushi sky, reliable, reasonable, and a good place to take people. Its not the best sushi in Toronto, but its the one I go to the most often.
The service has been decent, never had a bad experience. Sometimes its quite difficult to get anyones attention, and the staff will go long periods without ever checking on tables but sometimes the staff are super attentive at refilling water/tea.
Sushi is good, tempura alright. Salads are always the same desultory lettuce with ginger dressing that every japanese restaurant in Toronto seems to offer. I prefer it to the many of the others in the area.
They have increased their prices, so its no longer quite as competitive as it once was. (2014)
