This space is absolutely gorgeous inside! It had all the right amount of Greek decor! The food was good, the Avgolemono soup was my favorite, I o ended up ordering another cup. My only complaint is that the ambiance was kinda “sleepy” I would have loved to hear music welcoming me in and liven up the space, but overall, I had a good experience and will be back to try more plates!

WOW! Kostas Opa is back! After 10 years since Costas in Fremont closed, I am so happy that they reopened a couple of months ago in close-by Wallingford! The avgolemono is just as I remembered, absolutely delicious! And the gyro sandwich was also good. The look and feel of the place is very close to the place I would frequent in the 80's and beyond. UPDATE: I went back with a few colleagues for dinner and work discussion and had a great time! Great food and service!

Great atmosphere. Couldn’t get thru more than a half cup of coffee before the waitress refilled, stellar service. Highly recommend the California Benedict, it was just what I needed. No notes, easy 5 stars.
