Finally i got a chance to eat sushi at Sushi Ya. There r 2 locations which is not far one another. One is in Tebet n the other is at TIS Square, Pancoran. We r choosing Tebet one. Its very difficult to find parking here... i have to turn back 3 times n decided to park few meters from the restaurant.
The restaurant is small but quite good atmosphere.
The range price is average n they have many kind of sushi. We ordered mostly Salmon fish. The taste is quite good.
I will choose this restaurant if they have a parking land off course.
