Looked this up on trip advisor right before going. Also went to the website and was pleased to see a children's menu.
We showed up, and the waitstaff seemed pleasant but struggled with basic English. They also had no knowledge of a kids menu and didn't know how to bring me plain shrimp and plain beef with rice. I had to buy a salad entree with shrimp minus everything but the shrimp. I kind of have a hard time faulting restaurants for not doing substitutions but given they posted a kids menu then didn't honor one it was a bit frustrating.
I could have let that go but the service was awful (it appears from our observation that their staple is take out orders). They then brought our entrees one at a time and about ten minutes between each(not exaggerating), with my youngest daughters coming last and after asking about it four times.
So the food came, it was good. Nowhere near enough to overcome the poor service.
I would say if you want Vietnamese food, order out or go somewhere else.
