The service can be atrocious and the staff can be rather laissez-faire and unfriendly. I think the staff could use a lot more training on how to be decent servers.
I think they need to try harder if they want to stay in business. The food is OK if you've never had Korean food before. If they want to cater to people that know Korean food, they need to be a bit more meticulous. They should serve some basics that are normal in Korean restaurants, such as tea. They should also have some Korean pancakes, better choices of side dishes. The spicing and marinade is rather bland for Korean food. I think they could ask the customer what level of spicing they would like.
