If you send a PM message to OhioDisneyLover, she can give you her thoughts. She loved it last year and is making a trip over from the WL to eat at Maya again (unfortunately, although we've stayed there eight times, we've only eaten breakfast there once and never dinner).
We tried Maya Grill. I found the service to be incredibly slow. My ds fell asleep at the table waiting for the food. When the food finally arrived it wasn't even hot. By the time it had arrived we were so aggravated that we ate it anyway, who know how much longer it would have taken if we had sent it back. I hope it was just an off night or a bad waitress. I think the food could have been good if it was warm. I would maybe try it again if we were staying at CSR. I would not make a special trip over there just to eat at there.
