Restaurant looks good, and food is better than in many korean bbq places around.. BUT...
Nothing served on time. I takes forever to get your soup. Looks like waiters just don't want to serve it and hoping we will never ask for it. ONE STAR, thats all what its worth for such a crapy service!
Oh yah! after the soup is served there is no ladle or bowls... Was it done intentionally?
And at the end, instead of simply asking "You don't tip?" you should ask WHY?
