Due to an earlier thread (linked below), and of course in the sake of the Chowhound family, I tried the bbq banh mi at Mix Bakery in Chinatown. It was delicious! I honestly can't tell which I like better, the ones across the street at the famed Thai Binh market, or Mix Bakery. The meat was the main difference (TB's sandwiches consist of lean, grilled strips of meat, the ones at MB are more like sweet, caramelized chunks.) Make sure you check it out to see if you like it as much as I did!
