I've been visiting their Queensway location for a year now and I can say that I love their Ahi tuna Burger. However, the quality of it hasn't been consistent for the past 4 times. It's either without the "wasabi" or whatever green sauce they put on the sandwich or it is not cooked as requested, or the tuna is not spiced up at all (neither salt nor pepper when the burger is made). Please pay attention to that because this may affect the satisfaction level of your clientele like for example in my case.
