The Korean Grill House is pretty standard and self explanatory.
You buy some raw meat and cook it yourself on the grill (a bowl shaped grill that is built into the table) and when you think it's done, you pull it off the grill and eat it. Hopefully your food isn't undercooked. Hopefully your chicken isn't undercooked.
The place is nice, and while I know tons of people who love the Korean Grill House, the idea of going out so that I can cook my own food is just something that has never appealed to me. However, on that rare occasion when I'm in the mood for something like that, this is the place to go.
