This is probably not the best Thai food you're going to find in the city. However, I've been getting take out for 2+ years from here and the food is very consistent. Ingredients are fresh, and service is quick. Some dishes may seem a bit bland - but that is fine with me because it's easier to find dishes that the family will agree on.
When compared to other popular asian takeout places nearby, like Asian Legend, Congee Queen or food courts, the food does not suffer from the same awful aftertaste, and MSG overload.
The 5-star review is deserved due to the high degree of consistency, large menu choice (including hakka-fusion options) and quality of the ingredients relative to other asian restaurants.
