Sushi 101 lives up to its name. It's a basic sushi joint with not much of an umph to it and slow-ish service.
I found myself there one day in an effort to try something new (which is really hard because New Gen is just down the street) and ordered typical maki. Originally I tried to order some of their more exotic rolls, like the "vegetarian California roll" (cucumber and avocado, come on!) and but for whatever reason they couldn't really accommodate my requests so well.
I thought it was a bit on the expensive side but I noticed that everyone else at the place had heaps of food and I had only stuck to two items. Maybe I was at a disadvantage as the only meats I eat are salmon and tuna, but the other tables seemed pretty happy.
What Sushi 101 has going for it is that it is directly next to Sushi on Bloor. Either it will profit hugely off of the spillover from SoB (what a great acronym!) or it will simply be unable to compete.
I am not sure how long Sushi 101 will be around for but I think it will improve with age.
