I have since returned to Nam Wah twice since my initial review. Tried the Pho, incredible; the Ban Mi, extraordinary; and Com Tam Dac Biet (grilled pork chop, shredded pork, and steamed omelet), best pork chop I have ever eaten.
If you're not familiar with Vietnamese Cuisine, no worries. David will guide you in the direction you should go. Try this place out.
