That's a fascinating amount of carbohydrates I just ingested.
It's hard to screw up Mac and Cheese, but Macs tries its best. Mac and cheese is cheap, so in order to get the most from you, they overcharge you. Then, they slop a pile of their brand of glop onto a clever skillet tray, cover it with some toppings to disguise the fact that it's basically been sitting out for hours waiting for someone to order it, and then run it through a salamander to heat it up. The end result is acceptable, but it ain't great.
I'll probably go back, but not too often.
