Oh, don't call me stereotypical, but I'll always order fish & chips when it's on the menu. That would probably be my favorite regular food, saying of course that flan is not a "regular food" but a dessert food.
Oh yeah fish and chips are great. Good I'm in New Zealand. Another one of my favorites is pizza. I really love pizza.
I love hamburgers, no matter where they're made. I prefer the meatier ones not from fast-food chains, but even those are good if you get a double or a triple burger.
