McDonalds is selling the new black and white bun burger. The color is inked by squid ink. It was recently release in spring and already Americans have been thinking of bringing in the new burger to the US, it's become very famous and has cached many consumer's attention.
It probably would be very successful in the us since people are always ready to try something new. as long as the taste is still the same or better it will remain as America's top fast food restaurant.
