In-N-Out Burger

The Double Double is probably the most ordered burger from In-N-Out Burger.  I recall my uncle telling me how "juicy" they were.  But after ordering several of them recently on my trip to San Francisco, I couldn't help but notice that juicy really meant "greasy"!

The burgers are wrapped twice in paper, but look at the bottom photo of the inner wrapping.  Also look at the second photo and notice the sheen on the buns.  I'd call it a bit greasy.  What do you call it?

Still, the burgers are pretty tasty.  Compared to Five Guys burgers, the cost is more reasonable as well.  Which do you prefer?
