The brisket and meatball pho was large but bland at first. However, after some fish sauce, sriracha, and tearing up the basil leaves into the soup, it got very tasty. The brisket was flavorful and the meatballs were alright (though to be fair I'm not a huge fan of the meatballs at Pho 14 either). My friend had the beef eye round and meatballs, and enjoyed the beef eye round especially.
We also got the vegetarian summer rolls, which was also a bit flavorless -- I think the meat version would be better as the veggie version had a lot of unflavored tofu.
Service was friendly although a little slow and inattentive, but considering the place has only been open 4 days, that's not too surprising. There was a bit of a communication problem as well. It was very also inexpensive -- the most expensive thing on the menu was $8.95, and our dinner for two was $21, including a pot of tea.
I'm not sure it's better than Pho 14, but it is a good alternative, and they do deliver (minimum $15).
Pho Viet is at 3513 14th Street NW. Ph. (202) 629-2839
