Fast food

I must to admit I love fast food. I know it is not healthy but fast food is delicious.
If I hace to choose the best place to eat burgers I choose Mc Donalds and Burguer Kings and the best place to eat fries is definitely Juan Maestro but the best pizzas you can found them at "Ravera" (Ravera is my grandma's favourite place to eat). Fortunately I've never had bad experiences with fast food like Stomach pains  so I can't choose the worst place to eat fast food.
Although I love fast food I try don't eat it too often so I eat a burguer as once a month, but Being honest I prefer cook a homemade pizza than go to some restaurant or something like that.
My favourite fast food is a big cheeseburguer with a lot of cheese preferably and I love the cheese empanadas with ketchup.
What about you? Do you like fast food? Tell me what's you favourite.
P.D: If you have any advice for me I'll be grateful.
