Thim Hing Sandwiches has been serving sandwiches to Alief for at least a decade. The hole-in-the-wall shows signs of long-term wear with chipped melamine tables, chairs and floors that have seen better days, but their banh mi sandwiches are still top-notch. The secret is in the bread: They use just-toasted baguette bread that is thin and crispy, but not so crispy that it will cut up the roof of your mouth. Their xiu mai meatball and dac biet specialty banh mi with an egg on top is so good, you'll want to eat two. Small banh mi are $2.50, large are $3.50. Cash-only.
