There's no scale. Those could be very small plates.

I've eaten there before - they are large portions. (The place is Texas Longhorne....IMO, a hundred times better than Outback)

Last month I had a full rack of babybacks at the local Chili's. They're like a kid's portion. When the waitress came back less than 10 minutes after bringing the food, and saw nothing but my empty plate and a bag of bones, she said, "wow, those must have really been good!". I replied, "yeah, it was a nice appetizer".
