When seeking this essential Vietnamese street-food sandwich—baguette, fresh herbs, crunchy pickled daikon and carrots, Asian mayo and/or fish sauce-based dressing, fresh chilies and/or Sriracha and a protein of your choice—you’ll note that Dorchester has numerous quality purveyors. But this food-court stall adjacent to the Allston Hong Kong Supermarket gets our nod for its superb crackly-crusted bread and abundant fillings. There’s no better $4 lunch in town. Get there before late afternoon, when they frequently sell out for the day.
