All these stores dont exist in my country, you can buy watered down mountain dew, pop tarts for 10€ per box and the local fast food chains are mcdonalds, burger king and subway with an occasional kfc and a metropol city may have a pizza hut.
Sure its all marketing, but if im paying 10€ for a delivery pizza i at least want the box to look like a domino piece.
Most of US sweets ive tried were okayish, my favorite being reeses small cups. Was disappointed by how bad cheeze-its are, they were given away in stores as the sales were so poor and started with a money back promotion and still didnt get sold. Takis seem to have found their way, also taco bell (i know its tex-mex, but still a variety from burgers) opened stores in germany and the netherlands hoping it reaches a broader audience and can get more people attracted as i actually like the food given the price point and being somewhat more healthy than a quarter pounder with cheese.
Softdrinks on the other hand really do taste better. European Gatorade is cat piss compared to US Gatorade. Mountain Dew like i said is only the base version and even this tastes watered down. Hoping for a baja blast rollout in EU with taco bell making a push here. Dr Pepper is really awful in europe compared to american dr pepper but at the end its all about personal preference. Ive seen a lot of americans loving Moser Roth Chocolate from the european Aldi which is their expensive version of good chocolate but still at a discounter price. People that love this would probably die for godiva or leonidas chocolate.
