The old shake shack vs. In N Out debate. The burger aesthetically looks better than in n out and the buns are of better quality but I would favor in n outs burger over shake shack. The fries are about the same depending if you like a crisper fry (in n out) or a softer fry (shake shack). I would say shake shack's shakes are better because you can actually drink it compared to the thick in n out shake.
