This homey, slightly rundown restaurant is located in a homey, slightly rundown shopping plaza.  I recently read an article by restaurant critic Max Jacobson that identified it as serving the best Thai food in Las Vegas. In a curious twist of fate, Max was sitting at the next booth to ours obviously enjoying his complimentary meal with 2 associates.  \n\nWe shared orders of green curry and pad prik khing.  Penn makes the curry from scratch rather than using a prepared paste though it proved to be a bit thinner than what we are accustomed to.  The dish included a modest amount of skinless chicken, bamboo shoots, chili, basil and green pepper.   Pad prik khing is a famous Thai dish that we somehow have managed to overlook in the past.  It included stir fried skinless chicken, fresh green beans, chili, kefir lime leaves and curry paste. Both dishes boasted fresh ingredients and flavor warranting a return visit.
