After more than 10 years of serving authentic Greek fare to Tucson, Opa Greek Cuisine & Fun on Campbell Avenue has called it quits.

A sign on the restaurant's door quietly announced the closing, which happened about a month ago. The restaurant's phone is disconnected and owner Andreas Andoniadis could not be reached for comment.

Meanwhile, the Opa spinoff Opa Time Gyros and Salads at American Eat. Co., 1439 S. Fourth Ave., is booming. The restaurant, which is not affiliated with the original location at 2990 N. Campbell Ave., is proving to be one of the most popular of the six restaurants in the south side indoor food court.

American Eat Co. is open from 11 a.m. to 9 p.m. Sundays through Thursdays, until midnight on Fridays and Saturdays. Cafe con Leche coffee shop opens daily at 6:30 a.m.
