I have been going to Pin Kaow for a few years and it's good every time. The staff is nice and courteous, the food is excellent (to the point that I compare all other Thai places to them). My co-workers and I celebrate 95% of our birthday lunches here and at least 2 of us turn to Pin Kaow for Friday night dinners. I brought all my friends and family here when they visited and I am pretty sure I made a few of them become beef panang fans. A big plus is that it doesn't look / feel like a hole in the wall and the cleanliness is obvious.
