Came with my husband and two children. The wait for drinks Alone was too much and even worse for food. I expected high quality steak being a steak house as well as based on the very high prices, it was a disappointment. The chicken cordon...bleu was better but overall, a frustrating, slow and poor steaks for an astronomical bill!More

We were in town for the Half Corked race so took advantage of local restaurants. We made reservations for Diamond Steak House for 6pm on a Sunday. It was quite busy when we arrived, they tried to first seat us at a 4 seater jammed...in between two tables at an angle with the other patrons less than a foot away, could barely move my chair. We asked to move to a booth which they accommodated. Once seated, the server came around with menus and we ordered drinks, they seemed really frazzled and made me feel rushed. We ordered various steak dishes which were quite good. Sides included salad, baked potato and veg. Lots of toppings. While seated and waiting for our food, the table seated near us had two separate servers come to take their order, causing some confusion. They could use more staff I think, a common challenge these days. Food was good though.More

this was our first time here. We, the two of us, reserved a table for 5 pm to beat the rush and there was only 2 other tables. This is on Sunday evening. it started filling up around 545 pm. Could not believe how fast...the food came in under 15 minutes. We shared the roasted lamb and the mushrooms starter. Best food and such tender lamb we have ever had in a Greek restaurant. Only disappointment was no spanakopita on the menu. i have never been to a Greek restaurant that did not serve it. Dolomathes would have been nice too. We could not give this place a 5 stars because of the service which was inattentive and which we felt was unacceptable given the place was dead . No water poured for us like the other reserved tables that were empty and because our food was dropped off and then we were left with our server no where in sight during the entire meal with only one other table as the one had left. As a result we were not asked if the food was fine or if we needed anything else which would have been yes water please and another order of Tzatziki. I was about to take water off one of the other reserved tables besides us when she finally came by to pick up the empty plates, did not ask us how the food was only if we wanted dessert. we watched how other customers were served once other tables came in and wished that would have been our experience. Alas it was not and that is just how it went! Upon leaving our server was chatting with another server at the front and while we walked by a third server saw us and wished us a nice evening.More

This was our first time to the Diamond Steak & Seafood House and we were not disappointed! Staff was outstanding from the moment we arrived. Service was attentive but non rushed. The wine list was great. Food options as well. I had a 10oz Tenderloin...and it was done perfectly. Excellent taste. Another at our table had the Striploin and he said it was excellent. Portion size was generous! Overall the experience was great and I would definitely recommend this restaurant!More

We were just supposed to drive through Osoyoos heading to the Coast, but we decided to spend the night. While driving around town we spotted this restaurant and decided to try it The service was great, courteous and quick to check our passports. We had...a table off to the side of the Fire Place which was started shortly after we arrived. We made a reservation at talking with the person at the front desk at our hotel, and we glad we did. Now we don’t know for sure but it looked like those who made reservations were seated by the fireplace but we could be wrong. We made reservations for 5:pm and as we left just after 6:pm, the restaurant was very, very busy ( Wednesday) The food was fabulous and this was our first nice restaurant meal in over 2 years. I would highly recommend Diamond Steak & Seafood House. Fabulous Thanks for the great evening.More

I've been coming to the Diamond almost every year since I was about 5 years old, and can say that it is still, and has always been one of the better restaurants in Osoyoos. I love the food and the atmosphere, and have always had...excellent service. The pizza, lamb and prime rib are excellent, but you also can't go wrong with their appetizers. They have a lovely wine list for those who don't want to buy a full bottle, but if you do buy a bottle and don't want to drink it all, they will cork it so you can take it home. The prices are a little higher than I like to spend, but I appreciate that this is a tourist town where the restaurant still needs to maintain staffing levels to stay open in the off-season. This is a family owned restaurant that really works hard to train and keep their staff, and who do provide good customer service even during the busy summer season. Had a wonderful B52 coffee at dinner last visit and was way better than the local Owl Pub.More

We were waiting so long at our table, we had to get the bus boy to get us a waitress. The appies came at the same time as our mains. The Greek salad was flavourless, the calamari was also bland and the chicken souvlaki was...tough. Our waitress ignored us the entire evening and we couldn’t get out of there fast enough. Worst dining experience we’ve had in years!More

I don't think they have one. They are famous for their Steak, Greek food and pizza.
