Love going to Doan's because their pho game is always consistent. Broth is flavorful and they give the right portion of meat and and noodles. I've had their Thai iced tea a couple times, it can get a little watered down but they prob offer the best in the city. I've had Thai iced tea in other places and they can never get the balance right.
The ambience is very casual and you can always find a seat even when it's busy with lots of people. The staff is super friendly and attentive.
