L.A

• Rooftop Bar: Sounds simple - it`s on the rooftop, it`s got a bar. But this is downtown LA, and the crowd is here to go eyeball-to-eyeball with spectacular skyscrapers. Not your everyday rooftop bar. 550 Flower St. +1.213.892.8080

• Blue on Blue: You can phone ahead and book a private cabana by the pool, or you can just drop in and check out the bar where the Margaritas are as good as it gets. 9400 W Olympic Blvd. +1.310.407.7791

S.F

• Nectar Wine Lounge: A wine-lovers` paradise with a choice of 45 wines by the glass, and 800 waiting for you in the cellar. Sleek, modern decor and knowledgeable bar staff complete the picture. 3330 Steiner St. +1.415.345.1377

London

• Spoon at Sanderson: Ducasse never ceases to amaze. The building itself is an experience. Can the food truly live up to the extravaganza? It can. Miles ahead of all other kitchens. 50 Berners St. +44.20.7300.1444
• Nobu Berkley: Nestled in the sumptuous Berkley hotel, Nobu is the most seductive of Japanese restaurants. So let yourself be seduced, and discover why Mayfair has taken this pearl of the Orient to its heart. 15 Berkeley St. +44.20.7290.9222
