To describe Shogun in one word: average. I love Japanese cuisine, but I really won't be coming back.
On a Friday night at dinnertime, there were literally no customers inside. It's a pretty roomy restaurant with the normal 'Japanese restaurant' decor- some posters of beer, that one menu table mat you see at literally every basic Japanese restaurant, a waitress dressed up in a kimono. I overheard the chefs and waitress speaking in Korean, so it's not an authentic Japanese restaurant really.
The food came up pretty quickly, but the rolls were made haphazardly with the rice falling off, and the tempura batter was more chewy than crispy. The waitress mostly stayed behind the door, and on the way to the washroom my friend found her watching her k-drama. The chefs also disappeared after a while.
Nothing new, nothing special, but nothing bad happened either. I wouldn't recommend this place- there are better casual Japanese restaurants.
