I don't know what's the big deal about In-N-Out. Better than Mikkie-Ds, yes, but I put the burgers on the same level as jack and carl's jr, but a little on the small side. In-N-Out's frys suck IMO;
double cook them like all the others do (I'm assuming this is why I don't like 'em, many places now have "natural" fries, and they're way better then in-n-outs). The shake is okay, about the same level as jack's, but not quite as good as wendy's, and no where close to carl's.
Nation's, now that's a burger, and great pies. No hot girls, though.
All opinion, of course.
