In a large mixing bowl, whisk together the flour and the eggs. Gradually add in the milk and water, whisking to combine. Add the salt and butter; beat until smooth and try to get out all of the lumps.
Heat a lightly oiled griddle or medium sized frying pan over medium high heat. Pour or scoop the batter onto the griddle, using approximately 3 tablespoons of batter for each crepe. Tilt the pan in a circular motion so that the batter coats the surface evenly. You must do this quickly.
Cook the crepe for about 2 minutes, until the bottom is light brown. Loosen with a spatula, turn and cook the other side.
Fill your crepe with yogurt, ice cream or whipped cream (or simply fold them with nothing inside) and fold or roll.
Top with fresh berries, whipped cream and drizzle with melted Nutella. Serve warm.
