Saigon Sandwich is located at the corner of Turk & Eddy. Where is that you ask? The Tenderloin. I know you might not want to venture into this part of SF due to the overflow of street vagrants but do it because you will get the best $3 dollar sandwhich you have ever had.
Chicken, Pork or Fancy Pork are your only options and this is all you will need to expierence all that is Saigon Sandwich.
I love this place and will continue to trek through the tenderloin at risk of personal injury to eat this delicous meat and pickled vegetables.
