Apparently this place is well known for their cheap Vietnamese sandwiches, which are $2.5 for a small and $3 for a large.
You first choose the type of meat you want, and then they will fill it up with favoured, shredded carrots, parsley, and sauces. You can request to not add in the hot sauce because according to my friend who got hers with it, it's VERY spicy.
I got mine with shredded pork skin and it tasted really good. The small size was enough for lunch. Would definitely come again for the cheap food!
