There’s no missing the trend for Vietnamese food around the capital, and the opening of MOC Kitchen marks another stage in the cuisine’s growth away from its Shoreditch heartland. Tucked into the arches under Charing Cross Station, this modern, informal Vietnamese restaurant-cum-street food outlet is already doing a roaring trade. The popularity is hardly surprising: there’s something deeply attractive about cooking that’s full of bright, vibrant, natural flavours and colours, that’s fresh and zingy, but generally low in calories. Drop in for the familiar – slow-cooked beef pho, spring and summer rolls, and crispy salt and pepper squid – or try something slightly more unusual: braised catfish in salted caramel sauce, for instance, or sizzling wok-fried goat. You’ll be hard-pressed to spend £15 per person here, or half that if you’re ordering a takeaway.
