Do you diet when you travel? Or do you put your diet on vacation when you take a vacation? Sometimes the fragrance of street food is just too, too tempting. Lonely Planet went looking for the world’s 10 worst (or best, depending on how you look at it) diet busters, those high-fat, high-sugar, high-everything-bad-for-you creations that you buy at street stalls and wagons. They couldn’t stop at 10, though; they found 11. From Mexico’s gorditos to Quebec’s poutine to my favorite, Lisbon’s luscious custard tarts called Pasteles de Belém, here are Lonely Planet’s street foods most worth blowing your diet over.
