They are literally not the same thing. It's not even called instant ramen (generally just called cup noodle after the biggest brand) here and most people would make a disgusted face if you tried to compare them.
The one's I've tried say ramen on the packet...that's why I was hoping actual restaurant ramen was altogether different:
I've done some searches and there are some local Japanese restaurants that have ramen on the menu (I usually only order off the sushi menu)....I'll have to give it a try the next time we go to one of them. Sure, they may not be authentic..but it may at least allow me to get an idea for what ramen should taste like.
