Combine the chopped chocolate and milk in a stainless steel bowl. Rest the bowl over a pot of simmering water, making sure that the bottom of the bowl is not touching the water. Stir until the chocolate is completely melted.
In a frying pan, heat up the olive oil and saute the garlic until soft. Add the shrimp and cook until the shrimp are pink and just opaque. Add the salt and wine, and let reduce. Then add the parsley. Plate and drizzle with melted chocolate.
