(FoxNews) - A good wine bar welcomes all customers, from oenophiles in search of new releases to add to their cellars to others who can't tell the difference between a Cabernet Sauvignon and a Sauvignon Blanc. (HINT: The first is red, the second, white.) Some offer well-paired food, others a chance to meet and mingle with other grape fans, while a few house high-tech vending machines that dole out pours instead of snacks. At these top 10 wine bars across the country, you are sure to find a good selection of wines as well as knowledgeable, helpful staff.
