Had Shake Shack and In n Out within the same week, might've had some other burgs in between but I was on a pretty huge bender for about a month and it was all whiskey, so I don't remember a lot -
Best burger - In N Out
Best fries (not best, but 'better') - SS... but if they had all the Animal style shit on the SS fries, that'd probably even be better for most. In N Out fries were cardboard logs.
SS was mad greasy... the patties, the generous cheese, the buns basically grilled in suet, and then a pretty sad floppy piece of a greener lettuce (outer leaves of iceberg?) as opposed to those crispy leaved stacks of lettuce In n Out use that all seem to come from the inner half of the head, two little Roma tomato slices at SS vs two bigger slicer tomatoes at InO, plus raw+grilled onion option at In n Out sealed the deal for me. In n Out makes a cleaner, more sandwich-like burger, whereas Shake Shack makes this greasy burger/bread lump...
