The only thing I've eaten at McDonald's since being here in Korea has been ice cream. The 500Won ice cream cone to be more specific. Yum... and only 43 cents, who could complain?
Though I've not eaten there, that hasn't hampered their business. They stay busy and deliver. I love these delivery scooters. It's just a really good idea to get out of their way as they are buzzing down the sidewalks. ;)
