Living in Las Vegas, you hear a TON of people wanting to compare Five Guys with In-N-Out.  They are both of a higher standard than the normal fast food burger-joint.  My opinion?\n\nBurger = Still goes to In-N-Out.  That being said, Five Guys has a really tasty (and HUGE) burger.  Their standard burger is actually a double-burger.  One of my favorite toppings on a burger is grilled onions.  I don't know what they do differently, but theirs just don't have the same caramelized... \"goodness\" that In-N-Out has.  That being said, if you order a Bacon burger/cheeseburger you will get a LOT of bacon, and it is crispy and delicious.  The burger is a solid 7/10.\n\nAnd now, the reason you WANT to go to Five Guys...\n\nFries = Five Guys by a MILE.  I \"like\" In-N-Out's fries.  They are a strong 5-6 out of 10 in my book.  The burgers are magical, the fries... eh.  I've had a LOT better.  Five Guys fries are the reason to eat there.  Not only are they delicious, but even with a small order, you get a TON of them.  They are fresh-cut (yes, I know In-N-Out's are as well, but it's a different cut with a different flavor) and seasoned just right.\n\nThe fries will be the reason I go back, and I'll have a pretty-good burger with them while I'm at it.
