It's always a good idea, but even better on cold, rainy nights!
My friend ordered the kimchi soon tofu and I got the seafood soon tofu. What's good is that you can customize the level of spice from mild to extra spicy. Your order comes with a raw egg that you can add to your soup, if desired and comes with 4 standard banchans (kimchi, spicy radish, peanuts and bean sprouts).
Tip: even if you can handle very spicy food, don't get the extra spicy - it makes your food salty!
I like the simplicity of their menu and the service of their staff.
