this place is a korean restaurant across from lougheed mall
they have this thing on the menu where if u have 10+ people there are these set meals where u choose an appy,main course and dessert ( i think).. i think it ranged from like $10-$14 dollar per person? if u decide to go this route make sure you make reservations and tell them you can this special set thing cuz you need to tell them in advance..
if not you can just make a regular reservation for 30 people and order off the menu.. ive been to a party thats done it.
and be sure to wear clothes you dont mind smelling like shit cuz they will smell like shit when you leave
