Many people call kimbap sushi, but sushi it is not! The way I can describe it is that it is a more dense, salty version. And it's super cheap! I pay around $2.50 for a roll (approx. 10 pieces.)
This is at my favourite local kimbap shop - I had it 3 times last week for lunch!
This is the kimbap making station.
My favourite flavour at the moment is the pork cutlet "tonkatsu". It is made just like a sushi roll but with egg, ham, carrot, pickled radish and some other bits that I can not identify.
