I will go to In N Out all the time on my own dime. It's maybe the one place where I will spend my own money. But of course it is NOT a reveal shop. I won't go to Texas Roadhouse, Bubba's 33, 5g or any other place that pays me because why should I pay for it myself when they will pay me? But In N Out is the only place I break that rule because the food is still affordable and the experience is always much better than most any other similar option.
I have a Whataburger to do. I have been to it a few times, but don't go enough that I think they will even remember when I come back in 2-3 months. I'm not impressed with whataburger. it's a bigger meat patty, the fries are better than In N out and it's a bigger menu with more options, but value and experience for the price, i'm taking In N Out all day. I went to whataburger the day they had their 75 year anniversary and offered their burger for 75 cents. Place was slammed and outta control. Something whataburger cannot handle, but it would just be a normal day at In N Out because they handle that amount of volume.
I took my own sliced cheese with me to whataburger in a ziplock bag. I prefer quality cheese and not spending $1 slice for american cheese :-P
