today  we visited Gyeongbokgung Palace, Bukchon Hanok Village, Insadong, Ssamzigil shopping area, a Buddhist temple, Namsan Seoul Tower, etc.  It was a combination of taxi,  walking and taking the metro.
We had yummy pork belly BBQ lunch and red bean Bingsu for dessert.  We also made many stops along the way to shop and enjoy the scenery.
