Yes, the decor is maybe a little cheesy, and the restaurant isn't as bright as the two other Vietnamese restaurants in the same block, but the food and service are great.
I think their pho is quite good (very flavourful broths, especially compared to, say, bland Golden Turtle). Some of their Thai dishes are also well worth it: especially recommended are the thai mango salad--amazingly good and fresh--and the fried eggplant.
