I will travel to Europe soon. Where can I buy food more economically? De yi fa Rui

I just came back from Europe for a week and visited 5 countries 10 cities. Derek, France, Italy and Britain. Fruit is basically not too expensive. Especially cherries and blueberries, are much cheaper than in China. Blueberries are a pound a box, and cherries only cost a few euros. In short, it's not expensive, and I can't remember exactly how much. Prices in Germany and Britain are cheaper. France remembers to eat GROM brand ice cream, which is delicious. One ball is 2.5 euros, and four balls are 6 euros. The more the cheaper. Italian ice cream is also delicious! Pizza is basically a family workshop. Just order the most common margarita. Delicious, usually less than 7 euros. Pasta, seafood and ordinary food are very good. If you go to Nice, France, don't forget to have a seafood dinner. Of the five countries, I like Germany and Switzerland best. Swiss We live in ingeborg and the scenery is beautiful. We went to the snow-capped mountains. France is noisy, and the Italian railway station is a bit messy. Pay attention to fake "volunteers"
