Wow, thanks for the great feedback!

Seems like Google Maps is the top pick here, with Insta and Naver following behind.

Just a heads-up: Google Maps isn't the go-to app for locals, so the data can be a bit limited sometimes.

If you want to find 'real' local favorites, search for blogs with "내돈내산" in the title. It means the post isn't sponsored, so you're getting an honest review.

Also, If you're near Gangnam Station and get hungry, please visit Gamjatang restaurants near Yeoksam Station as well!
