I have been going to Sawadee for lunch for several years. Their food is consistenly good and they have an awesome wait staff. I have tried just about everything on their lunch menu, and have not had one thing I didn't like.
The only complaint I have against Sawadee is that when it gets very busy during lunch time they become overwhelmed, making it hard to get served and find a table.
Sawadee is one of the best Thai restaurants in Fayetteville. If you are going for lunch, arrive early. I highly recommend them.
