The Casino cocktail offers a distinct taste profile compared to a classic Gin Martini due to its unique combination of ingredients. While both cocktails feature gin as the base spirit, the Casino is distinguished by the addition of lemon juice and orange bitters, which introduce a citrusy brightness. The Maraschino cherry liqueur adds a hint of sweet and slightly nutty flavor not found in a traditional Martini. Overall, the Casino is more complex and fruitier, with a balance of sweet, sour, and bitter notes, compared to the dry and aromatic nature of a Gin Martini.
