The Moscow Mule is definitely my favorite specialty drink! I was introduced to this little piece of heaven by Oprah in the episode where she visited Yellowstone National Park. The traditional drink is served in a copper cup and consists of vodka, ginger beer and lime. The ginger beer is key though: a spicy version of normal ginger ale, it has a good kick! Anytime I see ginger beer on the menu, I always order a Moscow Mule. The other night at Bistro Nikko, however, was the fist copper cup I've had... kudos!
