The Moscow Mule is a refreshing cocktail that is perfect for a hot summer day in St. Petersburg. It is made with vodka, ginger beer, and lime juice. The combination of these ingredients creates a tangy and slightly spicy drink that is both refreshing and invigorating. The Moscow Mule is traditionally served in a copper mug, which helps to keep the drink cold. In St. Petersburg, you can find this cocktail in many bars and restaurants, where it is often enjoyed as a popular choice among locals and tourists alike.
