Open 24 hours, this beloved Koreatown eatery serves up authentic entrees, casseroles and barbecue to all sorts of characters at all times of the day and night. The food is inexpensive, but you may feel rushed, especially at lunch time or on the weekends. Still, hundreds of regulars can't be wrong. So what to dig into? Short rib soup, kimchi casserole and broiled beef with vinegar. But most importantly, the barbecue.
