I don't know what to say about White Castle sliders...
Realistically speaking, there shouldn't be any reason why a slider from White Castle should be appealing: (1) cheap, soft, over processed rolls which are reminiscent of what you can expect from the buffet at Pondegrossa, (2) over-cooked, greasy patty cut in a ridiculous, bite-sized 2x2 inch square, (3) a diced and sliced mixture of onions and pickles that are better suited for a hot dog or a stupid, McDonald's hamburger...
...And yet, they're surprisingly good. They have the faintest philly cheesesteak aspect to them that I find irresistible. And unlike a cheesesteak, which has sliced rib eye steak, a White Castle slider can't be nearly as expensive to replicate that flavor. I'd say they're on to something, but then again they've been doing this for a while. After all, some movie director even made a movie with the White Castle name on it which forever immortalized it in the bong-resin charred brains of stoners everywhere.
As far as I'm concerned, I only seem to dip into a White Castle every decade or so, but I was pleased to see that they have all kinds of different sliders these days: chicken sliders, jalapeno sliders, fish sliders, etc. Maybe next time I'll get a double cheese slider and a bacon & cheddar grilled chicken slider. Who knows? It might get really weird.
