I spent a few years in California where many good Vietnamese restaurants. After I moved to Pittsburgh, I have tried to find a good Vietnamese restaurant for Pho, beef noodle soup. I went to three other restaurants. Pho Minh, Vietnam's Pho, Tram's kitchen. But they met my dissatisfaction. Taste of Pho was not very bad, but their services were bad. Finally, I found my best place for Pho in Pittsburgh. I was so satisfied with the taste of Pho soup and service in Pho Van. Also I liked the price of Pho. Other three restaurants I went to, I paid around $10. But I paid $7.50 I didn't try other dishes but Pho. If you like Pho, just give it a try.
