We did a lot of stuff in those four days, enough to stretch over 2 blog posts.
We had really good patbingsu (red bean bingsu) near the palace.
Crashed overnight at a Jimjilbang (Siloam Spa)
Had makgeolli and pajeon (Rice wine and korean pancake), an excellent combo
Found the famous kalkugsu (cut noodle soup) stall that was featured on that Netflix show
and visited LOL Park!
