One of my favourite Vietnamese restaurants in Chinatown. The food is inexpensive but they don't cheap on quality. You get a lot for the money and it tastes delicious as well as authentic.
Their Pho bowls are very large and you'll probably have a large time finishing their XL size. Service is hit or miss but you shouldn't have much trouble on off-peak hours. They renovated the place and it looks much nicer than how it originally was.
Overall, a can't miss spot if you want to try out authentic Vietnamese food in the heart of Chinatown.
