First off, it's definitely not worth the 2 + hour wait. Wait like a month or so to go when the hype is over. My friend and I, being locals, drove from Henderson to the strip to try White Castle out. My family is from the east coast so I've experienced it before, but my friend hadn't.
After our long wait, I ordered a combo with 4 sliders, a side, and a drink and I ordered the 10 slider pack to take back home to my grandma. My friend ordered 4 sliders, a side, and a drink. I received my order fairly quickly after ordering.
I ate my food and waited an extra 30 minutes before my friend got his. I order 10 more sliders than he did. He went up 3 times to ask what was taking so long and the guy calling out orders said he had his ticket there and he would call him. Still nothing. He finally went and asked the cooks and they made his sliders right then and there. I don't see what the problem was.
Also, two of my sliders had a pickle and two didn't. The fact that they are already inconsistent is pretty bad.
