We have been to the Crystal Palace twice during lunch and are going again in June for lunch. We loved the lunch there. I remember they had the normal kids offerings (chix strips, mac n cheese). There were many salads and lunch meats. I loved the salmon, jasmine rice, and sliced beef. There were other dishes I can't remember because I pretty much stuck with what I mentioned. I am a very picky eater and was very happy with Crystal Palace.
We also like lunch time because it gets you out of the heat at "high noon". We prefer to take a break in the afternoon and come back later but don't want to be tied down to an ADR in the evening. We want to take it easy in the evening and get the CS then.
