Lux SkyBar is a rooftop cocktail bar in Hanoi's Old Quarter that looks down over Hoan Kiem Lake. It serves a whisky sour, and on request will make a tequila sunrise that is not on the menu. The bar sits on the top floor of Media Hotel & Spa, and happy hour runs until 8 p.m. It is a small mini bar with indoor seating, so it stays open on rainy days and is not a loud, crowded spot.
