OPSO is an all-day restaurant situated on the corner of Paddington Street and Nottingham Place in the London neighbourhood of Marylebone.
The main ground floor space is divided into 2 zones connected by a central spine that runs the length of the space. Beginning at the main entrance the spine is a coffee bar that casually welcomes diners and take away clients. Moving into the second zone the surface continues at the same height and becomes a high table for communal dining.
