There's a lot of choices available, but the so call "call/buzz for service" button doesn't work, even when the server tells you to use that when you need assistance... I've probably pressed the button 4 times without anybody responding, and finally had to wave at them to get attention. And this didn't happen once, I've been there a few times, and it's happened at least 3 times, until the end I just wave no matter what and have given up on pressing the button.
If they can improve on their level of service, I think I would give them another star.
