I have eaten here a few times every year. Was here on Christmas day, 2006 (yes, they were open!), because we got caught in the rain. Although there weren't many diners, the staff warmly greeted us. Moreover, they did not rush/scoot us out the door (we had 2 whole hours to waste away until the play!), and they were very kind.
Pros: plenty of seating, ROMATIC, great value, AUTHENTIC Thai
Cons: can be a little too dimly lit... but that's not really a complaint for me!
