Somme Wine Bar sits on the 11th floor of the Nex building in Ho Chi Minh, one more flight up by stairs. It serves white wine, mocktails and banh bo dessert, and a sommelier recommends wines to match the food. The indoor area has air conditioning, and outdoor seats look out over high-rise buildings and old French villas around sunset. Dishes do not arrive all at once, which breaks the flow of the meal.
