I actually felt validated when I read this thread, lol!
We've done 6 stays at Riviera since it has opened, we really love this resort~
When it first opened, Primo Piatto was AMAZING for counter service! It had fresh, unique offerings not found elsewhere. The food was always hot and delicious. The service amazing.
I'd say that each time we have gone, it changes just a little and not for the better. Of course Covid has made menu options smaller, but over time we've seen smaller portions, less attention to detail and preparation, and most definitely less flavor. The pizza used to be real pizza, vs. the now standardized cardboard flatbread ubiquitous to Disney. (Ugh, so disappointing.)
In the past, lemon blueberry pancakes were literally the best pancakes I've had. Same with the polenta with the breakfast.
The last time we stayed there was this past May, and while the food was overall decent (except for the pizza, ugh!), it was definitely disappointing with way smaller portions, and way less flavor. We were disappointed with the service we got as well~ twice during our stay we had less than friendly and welcoming service. Once was when my husband who got the pancakes for breakfast (mobile order) got one packet of syrup and asked my DD to go back and grab a couple more. When she asked the attendant who packages the mobile orders, she snapped at DD and said it was only for people who bought and paid for food here. When DD said we just picked our order up, she demanded DD go get the receipt to show her. I mean come on. I realize this is an isolated incident, but honestly, this is the kind of experience we've been getting from a lot of QS resort locations. Another incident was with an allergy order, I won't get into that, but my point is, they are. not as accommodating as they have been in the past.
I see a lot of people suggest to make Primo Piatto a destination spot for a meal, but I'm always thinking... no! It's not worth it, lol, unless you are right in the vicinity. A PP mentioned there is not a lot of seating, and that's true~ they actually removed some of the outside tables. I'm always afraid to be the voice of dissent for Primo Piatto because so many people love it (and I do/did too). But it's definitely not the same. Still better than some others, though.
However, if you do go, as others have said, I recommend the grilled veggie skewer/pita, it really is yummy, and the Greek salad (I get a side of kids' chicken nuggets and cut it up to add on top of the salad).
I also think Centertown Market QS at Carribean Beach actually has a few gems on their menu.
Just my 2 cents.
