Time Out says
Float like a butterfly and sip nectar like a bee. Head to this immersive butterfly experience at Grosvenor Square where they’ll be teaming up with multi-sensory visionaries Bompas & Parr. Discover the enchanting Lepidopterarium (that’s butterfly house FYI), which combines butterfly ecology, nectar tasting and an abundance of photo opportunities with the butterflies. As well as, mood lighting and iridescent décor to match the butterflies’ vibrant colour scheme.
