So fresh and such an amazing deal! All of the ingredients are of high quality, and the best part is the very thick crusty on the outside soft on the inside baguette they use! I hear Momofuku Ssam's banh mi is good, but if you want a cheap (under $4) sandwich from a tiny more ""authentic"" feeling place in Chinatown, go to Saigon. They have different varieties too of pork, chicken, meatball, vegetarian.... The people there are nice too. Also the sandwiches are so big that one could be enough for 2, lowering your lunch bill to a paltry 2 bucks.
Pros: quality, taste, price
Cons: atmostphere (it's in the back of a jewelry shop). The line can get long around lunch and over weekends.
