About OPSO
Greek hospitality comes alive in our Marylebone restaurant, where we blend traditional flavors with modern culinary techniques across two distinct dining spaces. At OPSO, we've created environments that feel both refined and welcoming - our ground floor greets you with natural light streaming through large windows, while wooden wall panels and our striking marble communal table anchor the space. Our Main Dining Room works beautifully for those initial moments of any gathering. We can accommodate 40 guests seated or 70 standing here, where many groups enjoy welcome drinks and our modern Greek tapas before transitioning downstairs. The space opens naturally to our terrace, giving your event an indoor-outdoor flow that guests particularly appreciate during warmer months. Descending to our Larder Room, you'll find yourself surrounded by our floor-to-ceiling curing chambers - a unique backdrop that sparks conversation. This lower-ground space seats 44 comfortably, or holds up to 80 for standing receptions. Despite being below street level, we've maintained brightness and warmth here, creating an intimate atmosphere that works especially well for birthday dinners and corporate gatherings. When you book both floors exclusively, we can host up to 80 seated or 130 standing guests. Our two bars - one on each level - keep drinks flowing smoothly throughout your event. We craft our menus around seasonal ingredients, presenting modern interpretations of Greek dishes alongside an extensive selection of Greek wines we've personally sourced. Our cocktail program draws inspiration from Mediterranean flavors, offering something beyond the expected. Whether planning a wedding celebration, Christmas party, or corporate event, we work with you to create bespoke menus that suit your specific requirements. Just a short walk from Baker Street and Regent's Park stations, our central location makes arrival easy for all your guests.
