"Opa! has always been one of my favorite restaurants in Campbell, which is probably why the wait is usually one of the longest in the downtown Campbell area, but it's well worth it! The drinks and the FRIES are definitely top faves of mine! I recently had the lamb gyro and it was delicious! The meat was tender, the vegetables tasted fresh, and the sauce was not overwhelming just perfect enough to give it the flavor that warranted a delicious gyro. Also I love the ambience! There's an outdoor fire pit, there are also heat lamps (if you are seated outside), and it's overall a great place to people watch too! Definitely recommend, if you're in the area or want some yummy Greek cuisine!"
