As a a Vietnamese, I am truly disappointed by the food there.
I tried a lot of things on their menu, but still, there wasn't anything close to the real deal. The pho was okay, the sandwich had a plain taste, the spring rolls were really oily, but still crunchy... The list goes on and on. But I guess the quality is okay for a Vietnamese fast food restaurant and it's cheap.
I'd recommend it if you want something cheap and a bit asian.
