Pros: We really enjoyed the food at CHH. DW liked the hummus sandwich very much. I had the fish and chicken combo -- in general, I'd recommend going with just the fish, which is quite good. The chicken is just he same ol' nuggets they serve everywhere.
Cons: It's CS, and pretty crowded at main meal times like most are. The lines and struggles for seating (especially when dealing with high chairs and/or boosters) can be off-putting, as with most reasonably popular CS places.
Regarding the QSDP, if you're looking at it meal-by-meal, CHH isn't the best use of a CS credit as it's on the lower end of CS, price-wise. That said, you can afford to be suboptimal on some meals if you're getting good value elsewhere during you stay.
