That's where they heat up the bricks!
I often wondered where the restauranteurs heated up the briquettes or brinks or rocks that they placed in the table for traditional Korean cooking...then I saw this. This place (not a good pic, it was from a taxi with my phone-camera) actually has a fire on the sidewalk right in front of it! The guy is pickin out a red/white-hot brick for the patrons inside. Only in Korea.

Fire in the hole!
