My DH frequently orders the chili at both places. He likes Carnation's better - larger chunks of hamburger meat, tomatoes and onions. He said the meat in the chili at Refreshment Corner is more finely minced.
As far as portion sizes, the meat loaf has been large enough for my adult daughter and me to share every time we've ordered it. I've also had the Romaine Salad with Shrimp and it was a generous portion.
