Vietnam tortillas: Bánh xèo are crispy, fried-then-barbecued streetfood snacks that I relish. This Vung Tau foreshore version has an ageing shrimp/fish sauce aroma that I’m not overly keen on, but the best I’ve tried had pork-and-veg filling, at a little cafe in a side street across from the Pullman Hanoi hotel. I added a dash of light soy sauce to those … superb. USD50c each.
