We came around 6:45 PM and line up was out the door. It was probably due to the holiday and everyone was in Vegas. I ordered a double double with onions to go. Even though there were a lot of people waiting to order, the cashier didn't rush anything but also repeated my order to confirm they got it right. I really appreciated that. However, the line up for pick up was just ridiculous. It was chaotic: people who just ordered stood in front of the counter even though there was already a line formed. There was absolutely no order here and I literally had to push my way through to get my food.
I enjoyed my double double. The two beef patties tasted great. The amount of the sauce was just right, it didn't make the bun all soggy and a mess to eat. It was definitely better than McDonalds. Other than that, it was nothing special. In-N-Out Burger is a great and cheap option if you are looking for a quick fix. However, that also depends on how bad the line up is, in that case, you might not be "in-n-out" at all.
