I always assumed if you wanted to save a few bucks on going out, you should have your friends come over to your house rather than go out. Apparently, you might be saving a little but probably not as much as you'd think.

Having four people over costs an average of $38 a person between food and drinks.  Going to dinner and a bar costs $62 per person.  That's a $24 difference per person . . . which isn't THAT massive.
