Korean Grill House is a chain. And as some of the other reviews have mentioned, it's not really Korean. It's Korean-style BBQ. This particular branch has 2 stories. Most of the seating is on the 2nd floor. Wait staff is attentive and friendly.
The food is good. The all-you-can-eat dinner is $12.95 Canadian dollars. Comes with thinly-sliced beef, BBQ ribs, pork, salmon, and squid. Also comes with side dishes. The kimchi is good, but the rest are just OK.
Had the mango sticky rice for dessert, which was terrible. The mango was unripe, and the sauce was way too sour.
