Nigella sativa aka black cumin, it must be the same one discussed hereRandom thing but they do have the capital grille line of restaurants here in the states… they also released capital burger line of restaurants. Its not organic or grass fed but supposedly higher quality burger meat like steak meat perhaps angus beef. Their burger bun’s actually have black seeds on them instead of sesame seeds! Although i dont know if its nigella sativa as I believe theres another common black seed used as a topping maybe black caraway seeds or something?
