I had heard people talking about Vietnamese sandwiches, and had tried it a couple of times and I must say I wasn't crazy about it. That is until Anissa took me to a small Vietnamese place near her flat in Old Street. These sandwiches are actually called Banh Mi, and what makes the ones at Keu so delicious is the bread: Crunchy on the outside and soft on the inside. Their classic Banh Mi is composed of baguette filled with spiced pork belly, ham terrine and chicken liver pate, and is amazing. I also tried some of the one stuffed with the spicy roast duck. This is the perfect place for a quick meal, and if you are not hungry (shame on you), you can have a glass of their freshly squeezed orange juice or their delicious Vietnamese coffee.
