The Nam Long is one of the worst restaurants I have been to. The staff are very rude and unfriendly, very impatient and pushy. The place is over decorated with Vietnamese/Chinese art, too dark, too loud and too smoky.
There is no non-smoking section available, which makes it very uncomfortable for non-smokers to eat in this place.
Apart from the Staff, the Manager as well is very rude and the drinks and the food are overpriced. There is no comfortable atmosphere in the restaurant and the space is not efficiently used, making it too crowded and one is almost sitting on the neighbouring table, as it is so densely packed.
Personally, being native Vietnamese, I woulnd't recommend anyone that wants to experience the great Vietnamese cuisine to eat at the Nam Long, but go to smaller, and maybe less posh restaurants, where they can be sure though to get good service and good food.
