As a korean monger fact is kim-chi is pretty much essential in every korean meal so if u go around their meal times your shit out of luck as i was told a while ago what i'm told is off peak usually is opening usual 10 most places or even 24 hour places they swap the girls at this time and then they get lunch rush 12-2 then 4-6 is out of work rush then 8-10 is people out a little late on weekdays friday and saturday night is rush territory.
