For strip mall fare, this little Thai restaurant squeezed into Westwood Villiage is pretty good for what its worth.
You can eat in as they have about 6-8 tables but it is pretty small.
Your best best is getting takeout.
I highly recommend the Rice Noodles and broccoli.
The turnaround is pretty fast and the service eating in is good but almost awkward due to the size of the place.
I frequently order out and then go next door to QFC to shop a bit before picking up my food.
Another nice item is the Starbucks on the opposite side from Vatsana.
