Maru

This chic K-Town lounge is nearly impossible to find—look for the blink-and-you’ll-miss-it sign out front. Ascend to the third-floor drinkery via a freight elevator that opens onto a spectacular bi-level space with soaring ceilings and modern, wraparound banquettes. Bartenders shake upscale drinks like lychee martinis and mojitos, and Korean sojus are available in fruity flavors like mango. Shell out $250 and a five-person, soundproof karaoke room equipped with flat-screen TVs is yours for the night.
