The Flower Burger team always look for natural ingredients and colourings to give their burgers the signature vibrant rainbow colours. They use turmeric, beetroot, and spirulina to get the yellow, purple, green and pink colours for their in-house buns.

The kaleidoscopic interior matches the colours of the burgers while creating an atmosphere of the ’70s hippy culture and clubbing world. Flowers dominate not only the walls, but the ceiling as well, symbolising of love, joy, and positivity.
