SMG is a great concept where you can eat and drink while watching movies, kinda like the Ipic theaters. We used a groupon I bought a few months back. Unfortunately, we showed up a little late, so could not get the "reserved" seats that everyone was mentioning on the reviews. We ended up in the general admissions seats which are like executive office chairs. Only thing is they don't recline and don't have much lower back cushioning. But the seats are pretty comfortable nonetheless.
I can see how it can be distracting to have servers going in and out a lot of the times, but I felt like they servers were very courteous and tried to be considerate while talking or moving around.
As for food, we ordered some drinks and the cookies which were good, although quite outrageously expensive. But this is expected as a place like this.
Overall, it was a good experience, but not sure if I would be coming back. It didn't really wow me and I could just do away with good ole regular harkins. I imagine the food here is probably not that great anyways.
