Blue Bar at the Taj West End
Teak floors, a tiled roof, and a setting amid gardens and pools give this open-air bar a Southeast Asian flair. Hotel guests and sophisticated locals, most in their late twenties, throng the bar, ordering creative martinis and mojitos from the best-trained mixologists in town. Race Course Rd.; 91-80/6660-5660; tajhotels.com.
I-Bar at the Park
Fashionable IT types fill the leather banquettes at this intimate space done in deep shades of red and, in the mood lighting, looking like an Indian-mod bordello. Try the Curry Flavors (citrus vodka spiced with fresh curry leaves) and the Wasp Sting (gin mixed with tamarind and green chile). 14/7 M.G. Rd.; 91-80/2559-4666; theparkhotels.com.
Library Bar and Lounge at the Leela Palace
Techies, American and otherwise, come to sip Cognac and single-malt Scotch—perhaps with a Cuban cigar in hand—at this clubby spot, filled with antiques and vintage books. For a change of scene, head across the corridor to the courtyard. Airport Rd.; 91-80/2521-1234; theleela.com.
Liquid at the Ista
This mellow outdoor terrace lounge is great for a serene evening of long drinks and gourmet snacking. The soundtrack, which changes nightly, includes a Persian percussionist, live bands playing covers of popular Western songs, and resident DJs spinning pop and hip-hop. 1/1 Swami Vivekananda Rd.; 91-80/2555-8888; istahotels.com.
