Just some context, if you go out drinking in Korea, it's pretty common to move from spot to spot throughout the night. One night could consist of maybe going to at least 3 different pubs and bars. For example, start off with dinner with drinks at a restaurant, go to a pub and have a round, then go to another bar and have a round then finish up at a noraebang and drink there as well. A good example actually is Psy's Hangover video.
So when Nicole says that she stays in one spot all night, it's not uncommon but not typical either.
