I've been going to Akropolis since it was put into the Arboretum.
The atmosphere has never been much to write home about. They close a week or two out of the year to usually clean/repaint the place but it always meets south of expectation. The tables are loud, the chairs they use heavy as anything and louder still. The service is usually wage (or sub) high school students and you know how that can go. That's not what it's about though.. it is the food right?
I think they have the best gyro meat in town. While it's not like leaving the country and having lamb/steak on a spit it is served fresh and well spiced. Others in town that you get gyros from will serve you some Cisco food service derivative which is freaky. Their Chicken and kabobs are also juicy and never dry.
You could rank a lot of complaints on this place if you weren't careful but I've been to them long enough and a repeat customer for probably 15+ years and they continually draw me back a few times a month.
