I had my first In-N-Out experience recently, and I have to say that I was thoroughly underwhelmed. The excessive hype may have had something to do with it, but I would take a Five Guys burger over it any day.
But really, I'm a thick burger guy. Thin patties are for chumps.
A Five Guys cheeseburger is equivalent in size to an In N Out 3x3:
Five Guys: 303g, 840 calories, 500 calories from fat, 55g total fat, 26.5g saturated fat, 0g trans fat, 165 mg cholesterol,
1050 mg sodium, 40g carbs, 2g fiber, 9g sugar, 47g protein
3x3: 392g, 860 calories, 500 calories from fat, 55g total fat, 26g saturated fat, 0g trans fat, 180 mg cholesterol,
1,880 mg sodium, 39g carbs, 3g fiber, 10g sugar, 52g protein
Way too much sodium in In N Out burgers.
