I think the portions are really big! I had the fried chicken both times we've gone, one time I got 3 pieces of chicken and the other time I got 4, enough mashed potatoes for me and my 2 ds' to share, and green beans. DH had the meatloaf and it was a large portion too. The fried chicken is really, really good.
If I remember right, the first time my sons shared the kids' pot roast and I thought it looked like too much for me. Should be plenty of food to share, then have the s'more for dessert! The 4 of us split that and had some leftover too....
