As is the case with most ghettos in a large city, immigrant populations will tend to move in and sort of give a facelift to the whole neighborhood. This is what is happening in the Tenderloin. In recent years, Vietnamese and Thai restaurants have established themselves in some of the most hostile parts of the area and have transformed them into a part of town that we now lovingly call, Little Saigon. Golden Era restaurant and Saigon Sandwich are a couple of places where people will trek from the financial district on their lunch break. These are not Michelin-starred restaurants by any means.
I once had a co-worker who bought two sandwiches everyday for two weeks from Saigon Sandwich. When I asked him why he bought two, he said he didn’t want to wait in their long line for dinner.
