I know many people love to hate chains. I love them. Let me explain why.
For the most part, every successful chain restaurant has a very distinct product that no other vendor sells. Take a look at a White Castle. Does anyone sell a burger even remotely similar? None that I know of. If any of of my random local burger joints disappeared I really wouldn't care - there are so many other restaurants selling a near-identical product in most cases that the departure of one burger restaurant wouldn't be a big deal unless it was your favorite.
However, if I were to lose White Castle, there is no place I know where I could get a burger so deliciously full of stinky onion steam that I keep smelling it the next day. This principle applies to every chain I hold dear. What other fried chicken joints sell chicken that is as ridiculously fatty and soggy (in the most delicious way) as KFC? Where else can you get a taco where you're not sure where the meat came from, but don't care because the fire sauce has obliterated all sense of taste in your mouth? Who else on this planet sells a burger that is as fantastically childish as McDonalds? Who's got a pizza greasier and soggier than Pizza Hut? Nobody, that's who.
This is why I love chain restaurants. There's something fantastic at every good chain restaurant that *no one* else has.
