Don't freak out that the best Vietnamese restaurant in Houston doesn't even serve pho or banh mi; there is more to Vietnamese cuisine than noodle soup and sandwiches. This tiny sleeper of a joint is one of only a handful of restaurants in Houston that specializes in banh cuon, steamed rice flour crepes, made-to-order in Chinatown since 2004. In addition, dishes such as bun cha ha noi (grilled pork with vermicelli) and ca thanh long (turmeric dill pan-grilled fish fillets) are specialties that should not be missed. Thien Thanh opens as early as 8:30 a.m. because many Vietnamese people enjoy these dishes for breakfast or brunch. Prices are very reasonable, but remember to bring cash.
