Two-bedroom Panorama suite with HUGE terrace, 34th floor, Column Tower, on Sukhumvit soi 16. Same building as the Long Table restaurant. I doubt there is a larger terrace anywhere else! Granted, two 2-bedroom suites "share" this terrace, but we have never had a problem with privacy issues, and have had catered Christmas Eve dinner with small group of friends and enjoyed the fresh breeze and beautiful views with no problems what-so-ever.
