Well, when you look at it realistically, the hot dog is not a special specialty, although I love it, it's delicious. Admittedly, the most popular street food in my country is burgers.
I like all of the street food, so if there's a chance for me to try them, I'd take no second thought to buy everything. Especially something that's easy to eat.
I like "gorengan". I think everyone in Indonesia likes "gorengan". Basically it is something fried, like tofu, tempe, banana, veggies, sweet potato, even only flour mixed with water. Very cheap.
