Empty your stomach before you come. Skip a meal if you can. We were so full that we had to pack one of the dessert for take away.
There were no menu, as soon as we took our seat and confirmed it's a vegetarian restaurant, the food started coming in a small cart. It kept coming and coming until our table were full of food. Mushroom, wild vegetables, kimchi, pumpkin, tofu soup, brown rice, cold noodle, red bean sweets, cookie, pancake, grilled mock meat, herbal tea, seaweed, tempura... Dishes can be refilled at no extra charge, but hey, there were already so many dishes.
The friendly staff speaks only Korean, so get a dictionary or a Korean speaking friend.
