Listed on the menu as a Hemingway daiquiri. While it wasn't quite what I would consider the classic version, it was quite tasty. Named for Lenin since it was mixed and consumed in Kazan, Russia where Lenin attended university.
2 oz. Bacardi superior rum
1 oz. fresh lime juice
1 oz. fresh grapefruit juice
.25 oz. simple syrup
It didn't mention it on the menu, but I assume they added a strong splash of grenadine and a cherry in the glass for garnish. I would drop the grenadine and instead add a small dash of Luxardo Maraschino.
Mix ingredients over ice, shake vigorously, and strain into a rocks glass over fresh ice.
