In the location's words:

BREADBOX offers you a meat and dairy-free experience as if it were the real thing. No animal cruelty, local ingredients and an eco-friendly identity down to the bone. Our menu of selected ingredients and weeks of research and experimentation will even make your Uncle Herbert question his eating habits. So you might as well tell him after the sandwich that he's just converted to the green side. We promise you, he won't suspect a thing at dinner!
