To prepare honey syrup, purée 1/2 cup berries in a blender or food processor; set aside.
In a small saucepan over medium heat, melt butter. Add honey and bring to a boil; simmer 2-3 minutes, then add berry purée. Continue to simmer 2-3 minutes more until syrup thickens slightly. Set aside and keep warm.
For each serving, place 2 waffles on plate. Top one waffle with 1/4 cup fresh berries. Drizzle with 1/4 of syrup, and top sandwich with remaining waffle.
