You will get varying opinions as to what is good or bad TS in the World Showcase. I will agree, in general, that the food in Chefs de France does not equal the food I had in Paris, and the food in Biergarten does not match the food I had in Munich. But I had instances in both places in which I was transported back to the country of origin by the taste or preparation of the food (alright -- I'll admit that it was the beer in Germany that "transported" me
).
Also, in looking at opinions, keep in mind that adults (and kids) have varying tolerances for eating adventures, and a life-changing experience because you try a new foreign food for the first time (prepared on American soil, with American ingredients and chefs) is not guaranteed. I like to try something new everywhere I go, and the WS is a perfect opportunity to do that in a concentrated setting. I think you can find "delicious" and "repulsive" in every WS restaurant (TS and QS) -- the fun is finding out which is which, according to your own taste.
Because of Chefs de France, my picky eater tried snails (after much encouragement), a perfect roast chicken breast, pate, creme brulee, and profiteroles. He enjoyed (and now looks forward to) 3 foods out of those 5 (all right -- two of the 3 are desserts). You WILL find something for a picky kid in every WS restaurant -- tacos in Mexico, cold cuts in Norway, chicken tempura in China & Japan, hot dogs in Germany, chicken kabobs in Morocco, pasta in Italy, a croque monsieur in France, fish and chips in England, and steak in Canada. It is a Disney park, after all. If you are a picky eater, you can also find safe and familiar foods on the various menus (or just stick with the Liberty Inn in America). If you want to go on a food roller coaster (like I do), you can also do that. And, who knows? You may wind up acquiring a taste for garlickly snails!
