lotr2 1) I think that sometimes it is cool to go to the fast food restaurants. There you can have a fun with friends. But it isn't useful for our health and of course home-made food is tastier. 
2) I like to eat some first courses in winter for example soup or borsch. When I come from school it is very nice to eat something hot. And some meat dishes. They give a lot of energy and help me to keep warm.
3) In my opinion eating in bed is bad habit. All your bed turns into a mess,  breadcrumbs under your side isn't a pleasant thing.
