I went to the Thein Anh in Houston a couple of times this week, and wanted to give a quick report. This place is the pho house next door to Pho Dung in the Hong Kong supermarket mall near Wilcrest and Bellaire.
These are the BEST Vietnameese sandwiches I've had anywhere in the city. The buns are toasted fresh in front of you, the meat is VERY tasty (we had the barbeque and chicken sandwiches), and all the ingredients were very fresh. The pho was very good, about the same as Pho Dung next door. The spring rolls were excellent and had a LOT of pork along with the shrimp. My son enjoyed his combination fried rice, as did mom and I. It was much more flavorful than average, and more fluffy and lighter, as compared to a typical chinese preparation.
Overall, this was a very good place, and the sandwiches were OUTSTANDING. This combined with the friendly, english speaking staff makes this my first choice for pho and sandwich in the Hong Kong mall.
