The New York times had an article entitled "The Vietnamese Sandwich | Banh Mi in America" today. It didn't spend a lot of ink on San Francisco, but had this to say about Saigon Sandwich:
"The space at Saigon Sandwich isn’t much to look at, but the banh mi — fresh, cheap and astonishingly delicious — may be the best in America."
It recommended the combo, where "fatty roast pork melts into creamy chicken liver pâté, buffeted by a noticeably sweet aioli and overflowing with cilantro leaves and stalks."
