Had Jack in the Box when we went to Hong Kong in the 90s and couldn't get enough of it, maccas and hjs seemed like crap by comparison.I never went to a White Castle there, don't remember seeing any around where I lived.
You get different burger chains in different states, there was no Jack in the Box on the East Coast, they had chains like Hardees instead which weren't as good.
I lived mostly in San Diego where Jack in the Box is based so they had a heap of stores around there.
