The best thing I ate in Saigon was this banh mi from Bánh Mì Bảy Hổ. I've eaten an average of (rough estimate) one banh mi a week for the last seven years of my life, as a loyal customer of the Banh Mi 11 stall in Broadway Market, then of Num Pang near Madison Square Park, then of Hanco's in Cobble Hill, and most recently of Viet Baguette in King's Cross (which is the best banh mi in central London). Within 90 minutes of my plane touching down in Saigon, I was eating, for the first time ever, a genuine Vietnamese banh mi, and I felt like the Christian villagers in Silence who, after years of praying together in a hut without so much as a Bible, finally have the sacraments administered to them by a real Jesuit priest. My main recommendation if you're ever here is to follow the advice of a blog called Vietnam Coracle, particularly this post.
