I've had lunch at Air Bar-B-Q twice, and the options were different both times. I'm sure that somewhat depends on what's not consumed in the dining rooms earlier in the week, so know that the main dish options can change. For instance, I've heard some mention there have been lobster burgers, but I'm certain that would be available only if they didn't get rid of as many lobster tails as they had expected.
My experience from the grill is that they had ribs, ribeye steaks, hamburgers, hotdogs, seasoned fish, chicken breasts, and shrimp kabobs. There were a few salad options like couscous and fresh tomato/onion. I think there was potato an/or macaroni salad as well. Other items included banana bread, a good variety of fresh fruit, cookies, and frozen yogurt for a dish or cone. Im sure there were other things, but thats what rings a bell right now.
I was happy with everything I got, and I can assure you it wasn't a hamburger or hotdog!
