While the food doesn't quite rank with a lot of other upscale Bangkok restaurants, the view here is well worth a visit, or at least come for a glass of wine or mixologist cocktail. The Roof Gastro is located on top of the Siam@Siam Hotel, outside on the roof, and there are superb views of the city and lights all around. The menu is international, plenty of pasta and meat and seafood items to choose from, and the gastro restaurant's big draw is its volcanic stones cooking setup, whereby the dishes are cooked on stone grills that can retain heat for 20 minutes, allowing diners to cook at their tables as well. There is also a Champagne and Wine Bar located up here, affording the great view without having to fork out for the rather overpriced dinner options.
