Late night food tours on a weekday?

We come in at 530pm on a wednesday and have a hotel booked near Seoul station. 530pm departure next day Every food or nightmarket tour starts before we can get to it they all seem to start at 7 or before. Anyone have suggestions for a tour? Or thoughts about tours in general

So far I've found One true that that seems to include a night market. Also they Will pick us up at the airport and drop is off at the hotel and does several major landmarks along the way.
