Look, it is hard not to like the concept; a place that pretty much has an extremely limited menu (burgers, cheeseburgers, fries and shakes) and excels at it. Down here in these parts, everyone is jealous (or Jelly as one of the young guys at work said) because you can only seem to find the In-N-Out in California and Vegas.
I-20 and Collins, not too far from our hotel, but at 9:30 in the evening, it was definitely beyond my normal dinner hour. We walked in to a fully packed restaurant and stood in line to make our order. The place looked clean, well organized and fully manned to handle the large crowd inside, and the drive-thru traffic that wrapped around the store.
off the record/menu method for presenting the fries covered in grilled chopped onions, cheese and 1000 island dressing. It looks positively disgusting, though if you were cruising the Vegas strip and had been drinking for half the night, I'm guessing this might be a way to go. I'm just going to say, give it a shot if you feel like it, but I've pretty much had my experience, and I'll pass.
I know many of the folks reading from outside the area swear by In-N-Out, and I hope you will come to their defense if I just happened to have a bad experience. But honestly, like the Animal style of the fries, when it comes to In-N-Out, I'm gonna pass.
