Liliha Bakery and Coffee Shop    Honolulu office workers know how a box of Liliha's coco puffs or haupia cake can brighten the morning. Cinnamon twists, Chantilly cake, chocolate dreams; pick up your box and walk out smiling. It's a formula that's worked for 57 years at Liliha Bakery, founded by Koo Takakuwa and now run by the second generation. The line forms before daybreak six days a week, for the service bakery and the trapped-in-amber 18-seat counter, where you can eye the butter mountain while you wait for your hotcakes or hamburger steak. A 24-hour bakery-and-diner is a rare find.  515 N. Kuakini St. 531-1651. Open around the clock from 6 a.m. Tuesdays through 8 p.m. Sundays. No credit cards. Checks accepted. $.
