Absolutely rude manager. Nowhere was it written (not made aware verbally either) that there is a 15% "service charge" on top of the meal price. I disputed the charge very politely. She argued that "this is how it works in Montreal" I replied with "tipping is not mandatory, it's not the law." To which she replied you have to! Absolutely terrible customer service, she told me I should not eat at K2 ever again before mumbling in CHINESE (they aren't even japanese at this place) to her coworkers. I know enough Chinese swear words to know she wasn't speaking highly of me.
At least I told her it was illegal and paid not two cents more than the written price. ( I gave her $0.01 tip for the good laugh I had afterwards about it)
Don't get scammed and have your food spat in.
PS. The food was actually pretty good to be honest.
