We've been to The Wave several times for dinner (as recent as last week)...but not had the roasted chicken so can't tell you how that is as I "usually" have the fish at dinner. We also think they have the best breakfast in WDW and lunch is pretty good too.
Feel free to check out my review on The Wave-the link is for a recent visit for lunch but you can also view breakfast and dinner if you scroll down to the end of the review (I am also currently working on updating dinner):
