The lamb gyro was great. Although the lamb was cooked well done, it didn't lose any of its juicyness. However, the entire gyro tasted a bit bland, which could be easily remedied with some hot sauce.
The service, as mentioned before, is not great. But st $4-5/ gyro, just treat this place as you would for a food court. With lower expectations for service, you could definitely bite into your gyro a little happier!
