successful and so focused are the Park HYATT HOTELS that once you’ve said the name, there’s very little left to add. The Park Hyatt in Tokyo, world famous thanks to its starring role in the film Lost in Translation, sets out the formula: modern high-rise architecture, sweeping views, sober contemporary interiors, ultra-plush amenities, and gold-standard service. To this one we’d simply add one word: Gangnam. Unless you spent 2012 shipwrecked on some desert island, you’ve no doubt heard of the upscale residential enclave that the Park Hyatt Seoul calls home.
