Oh please. People who eat at chain restaurants pile the kids and spousal unit into the grocery-getter and eat burgers or grilled chicken - same food and people as every other night. That's why they call them "family" restaurants. The only reason they go out is because they either don't want to cook or they forgot to thaw out the pound of ground for their Hamburger Helper.
Wait! I think I'm on a rant!
Mig posted awhile back that she doesn't order in restaurants what she can make at home - meatloaf, I believe, was the offending dish. Since I can cook most anything a restaurant has on the menu, I like to eat at places with atmosphere as Ginwoman said. I also like to eat at places where they actually prepare the food as opposed to opening a can or bag and warming it up like so much chicken a la king.
I like a water view. I like drinks on the deck. I like specials of the day. I like unique menu offerings. You cannot get any of that at a chain restaurant, and therefore I hate them.
