This was my first time here. The experience started out wonderfully and our server was really friendly and quick. I ordered escargot and the 10 ounce New York, blue rare with no sides except mushrooms. My companion ordered the breaded prawns for a starter and then the filet mignon with baked potato. Both meals were tasty and the steaks were exceptionally cooked. The atmosphere, however is not fitting a high priced steak house. It was loud, the tables were too close and the whole place just seemed cheap looking. It’s just not what I expected for the prices.

Dont read the bad reviews, We went in winter and it was phenomenal. Quality of their food was what you’d expect from a family member. Beautiful char on the lamb and steak. Calamari was prepared with love, not overly fried and no big chunks. Seasoning on the lamb was excellent. Excellent staff, plating was excellent. I find a lot of Mediterranean restaurants go sideways on overly large portions. This place gets a 10. Drinks, we ordered the pomegranate margarita, it was really well executed and a balanced drink considering they were modifying a classic. Highly recommend

Taste luxury while experiencing eating or having a drink at this place . The atmosphere WAS ELEGANT AND ELECTRIC ! The service was the epitome of professional and other restaurants should brush up and follow suit ,the drink menu consists of a wide selection of wines from $7000 export bottles of some of the finest selections in the world down to local and imported favorites and their Pina colada is top notch from what i tasted as well the negroni was probably the best I've stumbled across the food was 5 I had the diamond prime rib steak w/ baked potato they leave a huge condiment tray packed with sour cream bacon and green onions at the table with you the whole time witch I adore I dislike when the server is forced to stand there and ask if you'd like sour cream onions and bacon bits and dishes it out to you then leaves with the condiment tray . The napkins were towels thick and probably expensive I love that 5 over all a amazing experience dining out ◇ Go here !!! Maybe call before and reserve we may have been lucky seemed to be a real popular place , I am definitely going to be going here regularly and trying everything on their menu!!!!!!!

My biggest dissappointment is the reviews. This is an excellent restaurant in an ordinary location. Top of the line restaurants, diners, cafes need excllent cullinary support systems and a broad local foundation. This is Osooyoos, not Vancouver nor Seattle. Despite what might be on a menu, whenever you order in a new-to-you restaurant, consider where you are, what might be available locally - both food and personnel - and aim for their strong suit. This ensures you'll get the best they offer. We had a simple meal; salad (excellent dressing available at the front) red wine and mousakka. It was delicious and well priced. Our server was very pleasant and the overall atmosphere was perfect. We would certainly eat there again.

My kids used to like coming here but that was about twenty years ago and my mother decided we should drop in for a dinner. It was early and we were able to come in for their early happy hour specials which was 10%off on Greek, pizza, pasta and some chicken dishes. Being Friday evening there was also the prime rib which my mom ordered the small size medium rare. I ordered the BBQ beef ribs, the big bone ones that is part of the Prime rib section and mine was nice and tasty. There’s something about gnawing on a big bone that I like. I got the rice and veg and a side of soup. Everything was tasty and the style of food brought me back to how they used to remind me of dining here back when my kids were just babies. Now here is where it gets good. My mom was just pecking at her prime rib. She ate the soft fatty parts of the meat but the majority she just poked at and when we asked she said it was too dry and hard and over cooked. She kept asking us to try it but we were all too full. But I did get a bite and agreed it wasn’t medium rare at all. More like that dried out roast beef at the school cafeteria from the 70’s. We mentioned it to our server and she became my mother’s heroine. She showed it to the chef and got us a fresh plate from scratch medium rare and nice and soft and juicy! Wow! Such a wonderful person. Thank you. My mom kinda beamed inside because this made up and it reminded of when they used to frequent this place when they lived in the area. I remember dad coming here and they all remembered him. So this gave her good memories to add. Thanks for this nice evening. Stuffed bellies and sauntered out and went home happy.

This place is awesome! Super fancy, music is amazing, kind staff, beautiful plates, delicious food, perfectly seasoned, all the tastes of the food go together, the rice has a unique flavour Ive never seen anywhere else, the appearance and vibe of the place is positive and welcoming and warm. What I loved the most was the no wifi! They have a sign that says no wifi pretend it’s 1995 and talk with each other! It’s perfect for a family gathering to not go on their phones! We ordered the lamb chops and greek ribs and two diet cokes and it came to a total of $100, it’s a great affordable place! Their cool AC is perfect to escape the hot summer weather. Their staff is very kind as well! They gave us complimentary bread as well, it tasted perfect!
