Cornerstone, the flagship restaurant of the Park Hyatt Seoul, will host dessert buffets every weekend afternoon from 3 to 5 starting in January. They pride themselves in using natural ingredients and as little chemical sweeteners as possible–bringing out the rustic qualities of ingredients without muddying them down with sugariness. Macaroons, cakes, tarts, cookies, chocolates. There are also a few savory items, like ham croissants, smoked salmon croque monsieurs and Lavoche bread with camembert cheese. The 25,000 won price includes gourmet coffee or organic tea.
