I don’t know jack about different Italian dishes, but my first thought when looking at that dish with the “grits” and shrimp was that it looked like a French restaurant size serving not an Italian one. Either way I bet it tasted good. I did have shrimp fried grits in Nashville and I gotta say it’s one of the best breakfast meals I’ve ever had (and easily four times the size of the one in your pic).
In my European travels I found French food to be very tasty with a beautiful almost petite presentation; Italian food to be very tasty and overwhelmingly large portions served; German food to be very tasty with large servings as well and potatoes somehow prepared to fit in every meal; English food was, well, creative and sometimes quite good but sometimes quite mundane (I’ve never been a stew kinda guy). Obviously there’s a thousand exceptions to these generalities, but generally speaking, I could pretty much count on a restaurant dinner to fall into line with my expectations. Don't get me started on Asian cuisine. YMMV
