I have only been to District One twice. The food is nothing special. I have tried the Five spiced hen over tomato rice and pickled veggies. I thought there was no point in adding the pickled veggies in the menu since you barely get anything. I love that the tomato rice had a lot of flavor and also the hen. Tomato rice and hen were perfect. I have also tried their Oxtail Pho. I honestly think there is nothing special about that. The broth is just a regular Pho broth and the Oxtail seemed a little overcooked.
The menu is small compared to other pho places. I think District one is a Viet Fusion restaurant. They don't have everything a usual pho place would have. They don't offer many rice dishes or the drink desserts. So if you're looking for your typical Viet food, I wouldn't come here.
I would probably go to District One once in awhile for the Five Spiced Hen over Tomato Rice only. The prices at District One are higher compared to any other pho places in Las Vegas.
The environment is more hip and clean compared to other pho places though. It is very modern I would say. There is a bar and seating is very nice.
The service was good. I have only gone to District One once during lunch and early dinner (4AM). There were only 3-4 other parties the times that I have gone there.
