You could also take the shuttle over to T4 as well for options. Or it's a 10 minute walk via underground connector.
The AS Board Room is decent for a light and free lunch. Breakfast has a pancake machine and had some cereal, oatmeal, yogurt and bagels. Lunch had soup, salad, veggies, and some cheese and crackers out, as well as some fruit and cookies. I thought it was probably one of the best domestic free offerings I've seen out of an airline club yet. There were also some "for purchase" options like pizza too.
They had a bar, but I'm not sure if there are free drinks as I don't drink. They had a self-serve soda fountain too that was nice.
Ben Stein also was in there on when I was on my last MR.
