I've been to most of your list and they were all good. 'Ohana dinner: tons of food, lots of if meat. VEry good, and a fair number of veggies come with the meal, which is kind of unusual these days at WDw TS.
Whispering Canyon: both breakfast and lunch were very good. fun place esp for no characters. It can be a bit loud at times, but still fun. I'm not very into sausage gravy, but the skillet at breakfast otherwise has good food. The waffles they now serve are mini-Mickey waffles!
The Wave - wereally enjoyed our breakfast here. At 10:30am, it was very quiet. It was a nice break from the rushing and noise. The food was also very good. We found the healthy options very refreshing and yummy. For example, I was able to get an omlette with real tomato, feta cheese and spinach!!! Wow! You also can great coffee and a choice of top choice teas. I'm more of a coffee drinker, but Iwas really tempted to try one of the teas. I also love that you can get cocktails here made with fresh healthy exotic juices! (And yogurt drinks!)
I haven't tried Tutto yet, but we enjoyed everything else on your second list. Le Cellier has very good food, but can feel a little cramped, IMO. It's also a bit gray when it comes to decor. Coral Reef has the fish, which is cool. The Mahi Mahi was excellent, some other dishes aren't quite as good, but the Mahi mahi was outstanding! At Chefs, the filet wasn't as good as Le Cellier's but all else was very good. The desserts are great. Also, many standard TS options here come with green beans. LeCellier and many others don't have much for veggies anymore with entrees. On the menu it will say a veggies, but the nit comes and the veggie is only a garnish. If you want veggies in most paces, you have to pay extra and order them.
To summarize, I love the fun food at WDW, but I also get weary of a whole week of too much starch, not enough healthy foods. The meals that contain veggies other than salad can be a real standout, IMO. IMO, the food at WDW has definintely declined towards eliminating veggies for adults (Yet they have added them to all kids meals - go figure?)
