Eataly Rome: in decline?

As you might remember, we were in Rome this summer a week after the opening of Eataly Rome, the foodie's paradise. We were so enthusiast about it: great food, top quality products, good prices. So we decided to make it our Trevi Fountain (you know the deal: everytime you visit Rome you must go throw a coin in the Trevi Fountain so you ensure your return to the eternal city) and visit it everytime we are in Rome.

So last weekend we headed to Eataly to find out if it was as good as we remembered. And to be honest, we were a bit disappointed. First of all, the Roman Osteria where we had the delicious tripe has been turned (only for a month) in a Neapolitan Osteria  -nothing against Naples but we are in Rome, and when in Rome...-, then we found out that the water, which had always been free of charge, is not anymore so you have to pay for it, fair enough. The biggest disappointment was the tuna. You know we are fans of Eataly's tuna, so have a look at the tuna from Eataly Turin:

and the tuna from Rome this weekend:

After waiting for ages to be served, as you can see, the fresh salad, the tasty potatoes, coarse salt and mustard (not pictured) were substituted with... fennel... yes, just sone fennel that was not even cooked or garnished to be paired correctly with the tuna. The quantity of the tuna was reduced. The only thing that saved the dish was the quality of the tuna because it was tender and tasty.
I was still hungry so we went to the beer restaurant for a beer and a cheese platter. Since we hadn't been here before I couldn't compare it to any previous experiences but the beer was good. The cheese platter was also good, but that evening we went to another place I'll write about in another post and there I had the best cheese platter (stay tuned).

A positive thing that keeps us coming back are the prices of the wines, we still found the same good prices as last summer.
After we came back home, I happened to read this post on one of my favorite websites (sorry, it's in Italian). It shows a picture of a Despar truck in front of Eataly Rome, so, if they say that their ingredients are top quality from only small producers, what do they get from a low-cost supermarket like Despar (I'm praying they only get toilet paper and hand soap) ?
I don't know if it's true or not that the products are no longer top quality - the tuna and cheeses I had were very good - , but what we could notice were those aforementioned details. I'll be coming back next time we're in Rome, just to see where is it going.
