Yupha's is simply best Thai food I have ever had. Their green curry, red curry, phad prik king, and noodle dishes are all each the best I've ever been served. The included soup and salad round out an excellent meal. Service starts with a smile at the front counter, quick seating or addition to the wait list (they always fill up), and efficient order taking. All of the staff are dedicated to taking care of you well beyond what we should expect from a $10/head lunch place. I can't find a reason to go to any other Thai restaurant.
Only downside is that Yupha's always fills up at peak times. Those in the know know that a short wait is always worth the amazing food and service.
