We just stayed at the JW Marriott and enjoyed a restaurant serving duck. It is a whole roasted duck stuffed with rice studded with nuts & fruits. It was very different and delicious and served with a lot of banchan - their side dishes. One duck is enough for about 4 people - this is all they serve. The meal was about $65 US total. If you face the front of the Marriott, it is located in the strip of shops on the right - above the Express Bus Station. They are very busy and may be best to have the Marriott Concierge call to make a reservation. There were no tables the first night we tried and we returned the next day earlier.
