Gasoline & Rogers is a small Japanese ramen restaurant in a Jeonpo alley in Busan, next to Origin Coffee. It serves gyokai tanmen, shio tanmen, and tsukemen, with aburasoba mixed before eating and a rich seasonal horse mackerel tsukemen dipped in a thick sauce. The shop has about four to six seats, so a wait is common, and the tsukemen has sold out around 1:30 p.m. Noodle portions are small.
