We loved the Wave - probably our favorite meal on our recent trip.
I had the braised lamb shank with bulgur stew which was absolutely delicious.

DH had the tenderloin which he enjoyed.
Can't remember what the kids had but the chef and waitress were extremely attentive to our DS2's food allergy issues.
We also had an ahi tuna appetizer that was very good.
Desserts were good but not outstanding - I would rather have one normal sized dessert of my choice rather than 3 little ones - I am not too adventurous when it comes to dessert - I do not like anything really creamy or egg-heavy like flan, etc. and so had difficulty finding 3 that I wanted to try.
Pre-dinner cocktails were yummy (I had a couple of specialty mojitos) - especially needed with the week we were having (massive rains in mid-May)
Only drawback was that we had a relatively late ADR and with how tiring the trip was battling the rains, our kids were pretty cranky by the end of this meal. Then we walked over to the MK bus stops to catch a bus to POFQ in an absolute downpour!
Just editing to reiterate that the lamb shank was to die for - probably my favorite meal ever on all of WDW property, or at least tied with the popcorn coated fish at GFC (which I see is no longer on their menu!)
