    Smart Casual

    Why go

    OPSO is a practical Marylebone choice for an easy central London meal, especially for dates, catch-ups, or low-pressure celebrations. Book it for convenience and a polished address rather than for a clearly defined splurge, awards pedigree, or bottle-led dinner.

    About OPSO

    What should a first-timer know about OPSO? OPSO is a London venue that operates daily, with a midday opening window and an evening opening window, the dress code is smart casual.

    Use this guide as a planning note. Check cuisine, chef, price band, awards, menu format, drinks programme, full address, service details such as delivery or takeaway directly with the venue before you go.

    Book it for practical London planning

    OPSO is useful for logistical London planning. Opening hours are listed as 12–3:30 PM and 4:45–11:30 PM Monday to Friday, 10 AM–3:30 PM and 4:45–11:30 PM on Saturday, 10 AM–3:30 PM and 4:45–11 PM on Sunday.

    If you are comparing other London options, Lita, La Fromagerie, Fischer's are useful names to consider alongside OPSO. Choose based on the occasion, availability, the details each venue confirms directly.

    Good fit when the basics matter

    For a first visit, keep the brief simple: note the smart-casual dress code and opening windows, check any menu, pricing, accessibility, dietary, or group-size questions with the venue before you go.

    Do not assume an award-led or format-specific experience. Treat OPSO as a London option with daily opening windows and a smart-casual dress code, then make the final decision based on current information from the venue.

    The takeOPSO is built around repeat visits and neighbourhood custom; the description explicitly notes it working equally well for a Tuesday dinner between neighbours and a Saturday booking. That makes it a dependable option for midweek meals and weekend evenings when reservations are likely needed. Diners seeking a considered, produce-led plate with a serious Greek wine list will find it especially well suited to regular dinners and quietly special nights out rather than destination spectacle.

    The take

    The Take

    The Vibe

    OPSO presents a quietly assured take on modern Greek dining in Marylebone. The room reads as residential and considered rather than theatrical — a fit for neighbours and regulars as much as weekend bookers. The kitchen favours produce-led technique, and the wine list treats Greek appellations with seriousness, so the overall register feels composed and refined rather than showy. The result is a restrained, contemporary neighbourhood restaurant that leans into repeat custom and attentive cooking rather than big‑ticket presentation.

    Ordering Tips

    The menu rewards ordering some of OPSO's noted dishes—moussaka, lamb shank, grouper tartare, smoked eel and the baked feta cheesecake are flagged as signatures. Pairing choices should acknowledge the restaurant's focused wine list that highlights Greek appellations. Because the restaurant is described as the kind of place that attracts repeat local custom and weekend bookings, book ahead for Saturday evenings; midweek tables can feel more relaxed but still benefit from a reservation.

    How OPSO compares in Marylebone and nearby London dining

    Choose OPSO when ease and location matter more than a high-spend statement meal. Lita is the clearer splurge comparison, with Mediterranean and Iberian cooking at ££££, so it makes more sense for diners who want a more defined special-occasion brief and are comfortable spending more.

    Fishworks - Marylebone and Kima are better cross-shops when the group wants a more specific seafood-leaning plan. OPSO is the safer pick when the priority is a central Marylebone table that does not require everyone to commit to a narrow category.

    For a lighter or more casual plan, La Fromagerie is the better fit, especially if café energy is enough. Fischer's, at £££, is the stronger choice for diners who want a more defined room and Viennese identity without moving into Lita's higher price tier.
