Preheat the oven to 325°F (165°C).
In a medium bowl, combine graham cracker crumbs, 2 tablespoons sugar, and melted butter. Press mixture firmly into the bottom of a 9-inch springform pan.
In a large mixing bowl, beat cream cheese until smooth. Gradually blend in 1/2 cup sugar and vanilla extract.
Add eggs one at a time, mixing just until incorporated after each addition.
Stir in sour cream and heavy cream until the batter is smooth and creamy.
Pour filling over the crust in the prepared pan.
Bake for 50 minutes, or until the center is set.
Turn the oven off, crack the door slightly, and let the cheesecake cool in the oven for 1 hour.
Refrigerate at least 4 hours before serving.
Top with fresh assorted berries just before serving.
