Just reread your question and I may have missed the mark with my above answer…
Mexico - Not impressed with anything at La Cantina (other than the margaritas, which are good if you’re thirsty and it’s hot out). Think Taco Bell. Nachos are probably the best choice, for what they are. I know there are some light food items at La Cava (home of the best margaritas in WDW) - you might try that.
Norway - Just about anything from Kringla is tastey. The School Bread is very popular, but I find it very dry and probably my least favorite of the various things I’ve had there.
China - Lotus Blossom has the reputation of being the worst QS in WS - maybe in all of EP. I ate there once, “to have done it”, don’t remember what I had, and I have never been inspired to go back. Maybe others can help out here…
Germany - Bratwurst at Sommerfest and a beer. If you don’t want that much, than a soft pretzel. Their entry into the “mac and cheese” arena is the best I’ve had at WDW.
Italy - I have no QS experience here; VN and TI are both favorites. I’ve heard the pizza by the slice window, if open, is horrible. Tutto Gusto is kind of a TS with no ADRs needed and serves small plates - which is probably your best option for a light meal in Italy.
America - It saddens me that the stuff served here is what an international visitor might see as representative “American” food. I put it all in the category of carnival or fair food truck. It’s hard to ruin a funnel cake.
Japan - Everything I’ve had at Katsura has been at least quite good, and some has been excellent. The sushi is probably my favorite there.
Morocco - This is the one country where I like the QS offerings better than the TS. Tangerine Cafe is one of my favorite QSs in WDW; everything I’ve had there has been excellent. Spice Road Table is similar in concept to Tutto Gusto. Very tastey and more “upscale” than Tangerine; you can order a full meal or share a small plate.
France - Les Halles. That’s all I need to say. Sweet or savory it’s all excellent. If I’m not doing the FW RD rush, breakfast here is one of my favorite things to do in EP.
United Kingdom - Yorkshire Fish and hips is hands down my favorite QS in WDW.
Canada - see my notes above. IF they ever opened a QS that served the beer-cheese soup, pretzel bread, and poutine, it would likely have the longest QS food lines in EP…
Happy to answer specific questions if you have any…
