Perhaps people don’t go to “interesting” date destinations because it’s fun. In fact I doubt it’s fun at all*. Maybe they do that because they haven’t managed to open up in the more conventional settings.
In any case I have to say we’ve gone a long way from “is dating tznius” to “you shouldn’t go to Dave and Busters on your date”. Maybe if the OP had put it this way readers would have taken him more seriously. Than again, maybe being taken seriously was not the objective in the first place.
As to the main discussion: maybe Schok and Kalus Rosh is understood to refer to a type of forbidden relationship or interaction, rather than forbidden acts (like eating chomez on pesach) If you crack jokes with a female worker in your office, that’s a very different kind of interaction than making the same jokes with someone whom you consider marying in three monthes. I suspect that if someone can’t see that they have never been on a chareidi date.
* Personally I don’t really find dating to be fun, unless you get married at the end. It’s a very short lives fun in any case.
