I came in by myself around 6pm on a Saturday night, practically empty. Greeted warmly by Thai hostess/waitress Ana who thoughtfully sat me in a quiet area after seeing I had brought a book to read. The ambiance was pleasant with some indistinct music softly playing in the background.
I ordered the beef Massaman at level 7 out of 10 spice level and it came out reasonably fast with the standard accompanying pot of white rice. The flavor was robust and had enough kick to it to cause my eyes and nose to run a little. The portion size was sufficiently satisfying.. Although I admit I was in the mood for a Thai buffet that didn't exist during Dinner hours ;)
Overall a good experience, although unsure how a packed house would have affected the service.
