    Ultimate dining like no other
    Gus and Maria Tsigonias (owners) have been at The Diamond since 1998.
    In 1987 they bought their very own restaurant in Coquitlam BC and ran it for 10 years. After their 10-year lease was up, Gus and Maria relocated to Osoyoos to call home. The Diamond Restaurant came up for sale the very next year and both Gus and Maria purchased it in 1998 and have been proud owners ever since.

    • If your looking for a very satisfying meal at a fair price, The Diamond will not disappoint you. Greek theme and awesome pizza. We have enjoyed it for the past 7 years. Great service and ownership. A must visit when in Osoyoos.

    • Great service and even better food. The prime rib was huge, even the petite cut. House dressing is beyond delicious. Best part of the Osoyoos trip.
