OPSO [gr. ΟΨΟ] is an ancient Greek word for a delectable morsel of food, a delicacy. Our name reflects our concept. Inspired by traditional and contemporary Greek tastes, we create modern Greek tapas based on high quality ingredients, most of which are supplied directly from Greece. We focus on social style dining, food to be shared and enjoyed amongst family and friends in a laid-back, lively atmosphere.

This was our second visit to OPSO and we will keep coming back. Yes, it's not cheap - BUT the food is incredible. The tzatziki is the best I have ever had (the garlic and dill powder and creaminess!). The pita is perfect. The chicken...was so tender and well seasoned (and who knew gem lettuce could pack so much taste!). The baked feta with sesame seeds - OMG. And the signature lamb is maybe one of the best things I have eaten. As a bonus the cocktails are great, the wine list is more than adequate and the service is so attentive and friendly. We'll definitely be back again...and again.More

Some friends had raved about this place but we were disappointed. Some bread and tsadsiki, two mains, two beers, £105. Nice but nothing spectacular and poor value. Cross the street to the cheaper Greek or the two very good Indian places. All three are better...value.More

Hello I recently visit opso restaurant for lunch as it was my first time (and the last) and this happened Me and my friend we were looking for a table inside but it was full so we decided to seat outside as we found an...empty table As we seated one of the host ladies asked us with an attitude who told you to seat there and then she left Secondary we was seating there about 20 minutes without no one coming to take an order as they were ignoring us like we weren’t customers Thirdly the host lady passed next to us so we tried to order as we were waiting for a long but guess what she was ignoring us like the table was empty Finally we left the restaurant as we couldn’t deal with it anymore but I have to say that on this restaurant as good things you see from outside more badly is from inside Not recommend as you going there to give your money and receiving bad customer service Just someone tell me the reason why I have to visit that place again ThanksMore

Went there for lunch, for starters we had a fish of the day ceviche which was delicious and a stunning tzatziki which I recommend strongly. For main we ordered the Moussaka (deconstructed and good looking but still excellent) and lemon oregano chicken which was very...nice except for the roasted baby gem salad which I find a big mistake. Overall the food and service were both very good, but everything was a bit overpriced. Still recommend it.More

I’ve been a loyal Opso customer since they opened several years ago - food has always been really great (and still is good although portions have become much smaller and quality feels a bit lower). The biggest problem here is that prices have skyrocketed, which...is fine, assuming their service would have stayed great. It’s fair to say that Opso’s staff is untrained, unfriendly and creates a stressful dining experience. The second I put down my cutlery, whilst others are still eating, they start clearing. This is not what you’d expect at a place where an egg costs £19. Again, I don’t mind the price but the level of service makes this place an absolute no-go. Also - our waitress failed to smile once, spilled water on the table and didn’t even apologise, etc. Shame to see another great Marylebone institution heading towards its grave.More

We had lunch sitting outside. The menu on weekend is brunch so the options are mostly breakfast plates but there are some lunch plates too. Food is very well prepared and portions are OK.

Marylebone offers what so many London neighbourhoods
cannot: a village feel coupled with urban convenience.
Much of its success rests in its location. Wedged
between the northeastern corner of Hyde Park and the
southern end of Regent's Park and with a number of
Tube stations within easy reach, Marylebone is as
pedestrian friendly as Central London gets. The
bustling shopping mecca of Oxford Street separates it

I don’t know. I went for lunch without reservation, but I think is safer for you to make a reservation.
