I've always loved Korean soup. I got the Kimchi soon one, with regular spicy-ness. It was awesome! Not too spicy to the point where I couldn't taste anything, but spicy enough for the cold weather. If you're not the spicy type you can ask for mild. Or if you're up for a culinary challenge, you can opt for the super spicy option.
With $8 you can get four pretty well portioned side dishes (bean sprouts, kimchi, radishes) and a huge bowl of rice. They give out rice so generously. It's the perfect amount for the big bowl of soup they give you. Such a happy atmosphere there, the waiter who helped us kept smiling. All in all it was a good experience. :D
