Referred to as the 'tree place' by most of the internationals for obvious reasons.
Of course, the most important aspect of a restaurant is food - and it is great here! Traditional korean barbeque - for around 10k Won you will get one portion of meat (chicken, pork, beef available) plus various kinds of vegetables (mushrooms, lettuce, sprouts, kimchi and much more) tofu + soup. For an extra 2k Won they will fry rice enhanced with seaweed for you.
Nice employees, good quality food and the atmosphere make this an excellent restaurant, which might be crowded in the evening, thus I recommend eating there for lunch or in the early evening hours.
Also, I have to mention it is not the biggest place, I would say a group of 2 to 4 people should easily find a space and maximum up to 8 people might get lucky and find 2 tables with 4 spaces next to each other
