I live near Columbus, Ohio and in Columbus is a restaurant called The Thurman Cafe. All their burgers are 3/4 pound before cooking and as your enjoying it you end up eating it so quickly you don't even really notice. When I was younger and ate a lot more I got the Thurmanator. They describe it as, "The scene: Bottom bun, mayo, lettuce, tomato, pickle, banana peppers, 12 ounce burger, bacon, cheddar, another 12 ounce burger, sautéed onions & mushrooms, ham, mozzarella & American cheese, top bun served with fries and a pickle spear". I was full after that one for sure. Something about the onions, mushrooms, and ham combo does not agree with me I have learned also. It causes lovely intestinal distress. I thought it was perhaps because of the volume, but you can get it with a single patty and it does the same. I had issues like that with the Octoberfest burger at Red Robin in the past as well. I am not sure if they get cooked in beer or something and that and I are incompatible or what, but even if I was a big eater like I was I wouldn't want to experience that again.
