We're planning to do this in September for my parents and myself - using 4 DxDP credits. We sat next to a table of four last time (two parents and two little girls) and the four of them couldn't finish it! That being said, it looked like an amazing meal. The steak was cooked to a perfect medium and the side dishes/sauces looked hot and plentiful. It even came out of the kitchen sliced, so it was easy to portion to each person.
I hate throwing away food, so sharing the two-person meal between the three of us is a good solution!
