OPSO is a stylish restaurant and bar that celebrates the flavours, produce and social-style dining of Greece. Located just off vibrant Marylebone High Street, and a five-minute walk from Baker Street, OPSO offers delicious, modern Greek tapas and great cocktails. In the restaurant, there’s a roomy downstairs space known as The Larder. It can accommodate larger table parties and also boasts two semi-private booths – each of which seats eight – for a more intimate affair. With a tailor-made offering for events big or small, corporate or private, OPSO is the perfect place to celebrate a special occasion. The focal point of the basement is the two large curing chambers, which house Greek cheeses and a selection of fish and meat. Whether visitors are after a seated lunch or a standing cocktail party, The Larder can meet the requirements with a bespoke catering package. The dining space can house up to 60 seated guests, or 75 guests at a standing event.
