If you ever get to visit the amazing state of California, there are many different things that I would recommend trying out while you are there. When it comes to fast food, In-N-Out is the King!
Not only do they have delicious hamburgers and fries that shouldn't be missed on a visit to Cali, but they also have delicious shakes, and a secret menu! I don't know the secret menu too well but you can probably find forums about it online with a quick Google search.
I honestly don't even remember what was ordered by a California native friend of mine back in the day that was so good, but a normal Double Double (double meat and cheese) with fries will also hit the spot!
I wouldn't suggest visiting this restaurant if you aren't in the mood for burger and fries, because the only other available items are shakes, sodas, coffee, and milk.
