ACORNSTOR is a small fusion restaurant in Daehyeon-dong, Sinchon, Seoul, serving tuna gimbap, sundae bokkeum, and jeyuk dosirak. The tuna gimbap holds a generous amount of tuna, so one roll is filling on its own, and the sundae bokkeum can be ordered alongside it. Inside, a counter along the wall seats six people, and takeout orders are placed by entering through the door at the back and waiting. With few seats, a line forms before opening even on weekdays.
