It's kind of difficult to review a place when they gave you the wrong order but from what I gathered this isn't entirely authentic vietnamese food. It isn't terrible but I certainly cannot recommend coming here when there's far better Vietnamese options close by.
I ordered Vermicelli F5 which was with grilled chicken and spring rolls. My friend ordered for me and we're pretty sure he said the correct letter and number but a rice platter came and they refused to do anything about it. They said it's H5 and that's what they heard. Well we didn't do much about it because I was hungry and left it at that but this is pretty unacceptable.
Food wise, it was rather subpar. The bbq chicken was not the variety you would get at many other vietnamese establishments and was oddly red in colour. The portion size could have also been better as it was a pretty small cut of chicken. The other item that came with it, I am not entirely sure what it is: I've never seen anything quite like it. It's ground pork inside with an egg roll around it. It's interesting in texture as you can definitely taste the vermicelli but it was quite dry.
