I enjoyed our dinner date in Vivere - The Nest in Alabang. The restaurant is overlooking the metro. The food is good and not that expensive. You can check the 360 Panoramic view here: http://viverehotel.com.ph/panoramic0.html
71 Gramercy in Makati, one of the most romantic places I've seen in Manila. By the way, it's located on 71st floor. Love their roof terrace!
