Great food - very fresh fish (maybe one of the freshest in Toronto) and a lot of delicacies.
I have been to Japango on numerous occasions - both for dinner and lunch. It is an excellent place to drop by for a quick lunch or a nice casual, authentic meal. The clientele is predominately, yuppies.
My favourite are the chirashi sushi and Japango maki - the sauce has bite! I also try to order the chef's special, which changes daily according to the catch of the day.. The baby green salad is also very good - it accompanies the set dinners (I hate iceberg lettuce).
The only drawback in my opinion is that it is extremely tiny and you will be squished next to your neighbour. If you are ok with this, and love great, authentic Japanese food, definitely worth a try.
