OK, in Opa's defense, there is an Open sign facing Jefferson Rd...a very small open sign. There was only one other car in the parking lot when we arrived around noon on a Sunday. We thought it was not open yet (there were several cars around the side where the kitchen/wait staff would park). We drove by the front and read that the hours for Sunday were 11 am to 9 pm, so we went inside. We are glad we did. We tried a few standard items - Tyrokafteri (spicy feta spread), greek salad and a gyro pita with yummy lemon potatoes. The food was excellent, the service was top notch. I hope the restaurant does well, but I think it needs to be a little more inviting.
