We ordered entrees, mains and drinks for just short of 70k won which was quite reasonable.
The papaya salad was authentic, pad thai used tamarind sauce which made it yummy and vegetarian green curry had lots of vegetables.
The service was terrific with the staff constantly refilling water etc. they also spoke good English.
We ate dinner early just before 7. When we went to leave there were a dozen people waiting for tables - obviously this place is popular! So would recommend to make a booking if you're coming at 7pm or later.
