Lost - DTLA is a rooftop lounge in Downtown Los Angeles that serves cocktails and tacos. A DJ plays old hits and Afrobeats, and tacos are sold alongside the drinks. At 9:30 p.m. the venue is quiet, and from 10:30 p.m. it gets crowded; reservations are easy to get. There is no dress code sign at the entrance, and sneakers are turned away.
