My In-N-Out Theory™ is that west coast ppl grow up w/ v different flavors & simpler/healthier/fresher foods so it tastes good to them (or "us" I should say) but east coast people are used to foods with more sauce/spice/grease so they're obsessed with Shake Shack. Also nostalgia

I also feel like it’s a “thing” to call In N Out overrated - it’s simply a completely different thing than Shake Shack

Those fries are cardboard you can’t tell me otherwise
