Hamburger battle: Five Guys v Shake Shack v In-N-Out MAY 18 2011
In a somewhat flawed test -- e.g. part of the In-N-Out burger package was confiscated by airport security -- the Shake Shack beat Five Guys and In-N-Out in a Serious Eats taste test.
Clearly the In-N-Out burgers making their trans-continental trip by plane would be at a disadvantage to the made-fresh-in-the-same-city burgers from Five Guys and Shake Shack, so in order to compensate for this, we made the decision to handicap all three burgers by the same amount. After a careful synchronization of watches, burgers were ordered from their respective establishments at precisely 1 a.m. Greenwich Mean Time (that's 9 p.m. EST, 6 p.m. Pacific) and not tasted until the following morning.
I used to be a big In-N-Out fan (their burger is still a great fast food burger), but the slightly more upscale Shack Burger is my favorite burger in the whole wide world...it is indeed, as the article states, "a marvel of beefy engineering".
