"San Francisco is full of incredible sandwich spots, but if you can only fit one sandwich into the agenda, make it a bánh mì from Saigon Sandwich. The cash-only institution is just outside the Tenderloin’s Little Saigon, and has been around for decades. The secret to their longevity? Every sandwich, from the tender roasted chicken to the fall-apart meatball, is an umami bomb stuffed in a crackly yet soft roll. That, plus the fact that these $5 bánh mì cost less than a single iced latte with oat milk. " - julia chen 1, lani conway, ricky rodriguez
