As for me, I support the idea that the service is very quick in Fast Food Restaurants. 
As it comes from the name of the restaurant, you go there to get a quick snack.
If you don't have much time or don't want to wait you go there and get a sandwich or something like that so as not to feel hungry any more. So, some more "for" are as follows:
-The food is rather cheap
-The people working there are usually young and friendly
-The food is usually fresh
Of course everyone chooses his or her Fast Food restaurant but the chains they have usually offer the same dishes all over the world.
