Standing in the shadow of the George Washington Bridge is Fort Lee and it's thriving Korean community. The most famous of its soon dobu (or natural/soft tofu) places is near the end of Main Street downtown.
You have to be ready for a little grumpiness when you go to So Kong Dong. The people here are monotone, and very unhappy to be working. At one point two employees were even yelling at each other, making it harder to get the attention of the people that hardly respond to anything and certainly not to any pleasantries.
But the tofu soups are good, and that is what is important. The kimchee beef tofu soup ($9, below) is the best in my opinion, a boiling combination of spicy tofu soup, vegetables, and meat. As always, you have the option of breaking an egg into the soup to cook, and the rice they serve with it is really good.
