I was quite surprised when I saw the low ranking on the trip advisor forum. It is one of the most popular thai restaurants in charleston (if not the most popular). I have always had a good culinary experience at the restaurant. The only unfortunate aspect is they don't take reservations so you may need to wait awhile.
