At the foot of the Grade I listed iconic building of One Marylebone there lies a restaurant within bespoke designed Greenhouses. The event hire spaces at One Marylebone also include the Soane hall, the Galleries and the Vaults under the church. On top of the dining experiences you can book their yoga and Sound bath wellness sessions with Xscape Studio on Mondays. Pop by their very own flower market in the courtyard, curated by Floward.

The Greenhouses restaurant menu represents all the strong and vibrant flavours of the Mediterranean. With a sharing style menu there is nothing more that your palate could ask for. Chameleon aspires to create a buzzing and lively ambience throughout all of the Greenhouses for your private hire events. The Greenhouse dining spaces are all individually designed with each one having its own unique floral backdrop.

Currently running as a prebooked private dining experience, you can choose between the two large Greenhouses for up to 22 guests seated dinner to 30 standing for drinks and canapes. We also have our 14 seater Greenhouse which has limited availability.
