This place is OK if you are in the area and just want a quick Korean bite, but there are much better options if you're OK with taking a slight trek down Yonge.
The place is large and fairly clean. Decor is modern. I'd say for the most part, it's all spacious and comfortable. The menu is fairly extensive and contains pretty much all the standard Korean menu items. I've never tried having Korean BBQ here so I can't comment on that. For their standard dishes, the quality is passable, but nothing particularly outstanding. However, their prices are higher than the average Korean joint, so relative to the prices, the food quality isn't up to par. I am not a fan of their banchan (side dishes) -- while there is decent variety, they tend to be overly westernized items that I rarely see anywhere else.
As for the service, I haven't really experienced any of the rudeness mentioned by other reviews. But the service is definitely lacking in pleasantries. The courtesy shown here is less than any other Korean restaurant I've been to in the GTA, which is odd. They also tend to be slow with responding to requests (e.g. for more utensils or side dish refills). There are some nights where it seems like they are just understaffed.
