I have never had lunch there, but we had dinner there one evening on our last trip. We absolutely loved it. We were hot and tired after a day at MK, and we were staying at the CR. DDs (then 4 1/2 and 22 months) were cranky despite their afternoon nap. Finally, DH and I looked at each other and said let's get out of here. We headed back to the CR, and decided on a whim to try the Concourse as a walk in.
We were seated right away with a very attentive wait staff. The pace of the meal was perfect. DDs meals were brought out before mine and DH's. We were able to cut up their meals and get them settled just as our meals came out. Just as DDs started getting antsy, the wait staff suggested the painter's pallet for them (great idea!), so DH and I were able to finish our meal in relative peace.
The monorail zipping through was also a big hit with DDs.
Definitely pricy, but still well worth it. Food (and drinks!) were awesome, pacing was great, and entertainment factor for DDs was wonderful. Definitely recommend.
